I know a lot of folks here use mob-rule to track visited counties, so you may have seen this page (https://www.mob-rule.com/faq.html), which lists some common questions and answers as to whether or not certain routes enter certain counties. It's far from exhaustive, though, so I thought this could be a place to add to this list with some you've encountered that aren't listed, or otherwise obscure examples that you know of. Inspiration for this was two-fold: the thread about routes with multiple crossings of the same county line, plus an obscure county entry that I discovered this weekend (more on that below).
Generally, a route should be within a county's borders for five miles or less to qualify. If it's much longer than that, it should be pretty obvious from a map that it enters the county, unless it straddles the county line or has some otherwise unusual context (in which case, please note it as such!). And please, limit this to state routes/US routes/interstates! Lower tiered roads, such as county roads, aren't in the TM system and are unlikely to be used on road trips, so they aren't relevant here.
My first two entries for NY:
1. Does NY 21 enter Yates County?
Yes. When I encountered an Ontario County line sign approaching Naples on NY 21 southbound, I did a double-take. Wasn't I already in Ontario County? No, it turns out that NY 21 passes through the corner of Yates County for about 0.7 miles, so you'll pick up a bonus county if you're following NY 21 between Naples and points north (a great drive for fall foliage, I might add).
2. Does NY 30 enter St. Lawrence County?
Yes. Short and sweet, NY 30 is only in St. Lawrence County for about 0.6 miles, but contains its junction with NY 421, arguably NY's most isolated state route, and some great scenic views at nearby Bog River Falls. It would be strange to clinch NY's largest county via the this short and isolated stretch of NY 30, but it is certainly in play.
VA-231 cuts through the northwest corner of Louisa County for approximately 0.2 of a mile. North of that segment, it's in Orange County; south of that segment, it's in Albemarle County.
Something tells me we may have had a similar thread in the past, but I don't remember what the subject may have been. I'll try searching for my username and "Louisa County" because if we have discussed it, I would have mentioned that same stretch of road.
Edited to add—Not quite the same thing: "HIghway With the Shortest Trip Through a Jurisdiction" (https://www.aaroads.com/forum/index.php?topic=28553.msg2572908#msg2572908) from 2021. So this thread is a little different in that it also asks about roads that just miss entering a jurisdiction.
I-84 very briefly crosses into Hampden County, MA in the town of Holland upon crossing in from Connecticut.
I-95 in Darlington County, SC

I'm guessing not too many county roads go into another county. :)
For Colorado, not that many close calls. Off the top of my head:
1. Does CO46 enter Jefferson County? No. The county line is its official end.
2. Does CO103 enter Jefferson County? No. Clear Creek CR 151 is its official end.
3. Does CO317 enter Routt County? Yes. Routt CR 29 is its official end, about 1/8 of a mile from the county line.
4. Does CO394 enter Routt County? No. The county line is its official end.
5. Does CO112 enter Saguache County? Partially. The westbound lanes are in Saguache County.
6. Does CO150 enter Saguache County? No. The state highway ends at the National Monument border, despite what Google Maps says.
7. Does CO150 enter Costilla County? No. It misses it by less than ten feet.
8. Does CO17 enter Archuleta County? Yes. It clips the southeast corner for about 1/3 of a mile.
9. Does CO127 enter Larimer County? No. It misses by about 1/4 of a mile.
10. Does CO2 enter Arapahoe County? Partially. The northbound lanes enter the exclave of Glendale.
11. Does CO470 enter Arapahoe County? Yes. For about 1/3 of a mile.
12. Does CO121 enter Denver County? Yes. There are some funky border lines near Bow Mar.
13. Does CO96 enter Otero County? Yes. For about 400 feet.

It's also worth mentioning that there are a few errors here and there as well. For instance, it says that I-294 doesn't enter DuPage County, Illinois, but it does (near the gore of the really long ramps / really short route that connect to I-88).
Also, here (https://www.aaroads.com/forum/index.php?topic=29373.0) is another thread on this same topic.
I-94 barely misses Chippewa County, WI.
WI 29 very briefly enters the northeastern corner of Outagamie County.
A more well-known one, US 56/412 comes within feet of the northwestern corner of the Texas Panhandle (Dallam County).
MN 23 crosses the southeastern corner of Lincoln County for a little more than a mile.
US 218 clips the southwestern corner of Dodge County in Minnesota for less than a mile.
MN 280 is very close to the Hennepin County line for its entire length, but the closest it gets is about 600 feet away from the border.
MN 97 ends about 1/5 of a mile into Anoka County.
MN 41 ends about 300 feet into Hennepin County.
MN 210 crosses the northern tip of Morrison County for about a half mile.
ND 54 crosses the Red River a few hundred feet north of the northern edge of Grand Forks County.
WI 29/32 barely cuts the NE corner of Outagamie County.
I'm pretty sure that's the first and only instance of two people mentioning Outagamie County on the internet within 30 seconds.
Some Kentucky examples -- I-64 has a near-miss of both Greenup and Lewis counties, and I-75 a close encounter with Owen County.
The WK Parkway has a short incursion into Butler County but there is no exit within the county.
Along I-79 in West Virginia, the route very briefly enters either Braxton or Gilmer (I forget which) before entering Lewis County. This is between Burnsville and Weston.
During the Marshalltown, Iowa meet in 2010, we visited the spot on IA 330 where the route clips the corner of a county so briefly that you can get both county line signs in the same photo.

I will leave it up to the mods if they'd like to merge, but FWIW I am viewing this as basically a compilation of these two threads, plus adding near misses. Basically, anything that would make sense to add to the Mob-rule page if you wanted to be more exhaustive and include state routes.

Ha, that is fair, but there may be occasional cases of keeping the same number across county lines.
I-75 barely misses Gladwin County, Michigan by about a quarter mile. Several people say they are missing Gladwin County on mob-rule but I wonder how many would have it if I-75 had clipped it.
US-12 used to just miss Rock County, Wisconsin by about 440 feet...until they put in the bypass around Whitewater.

Side questions on this topic.
Highways (that I know of) that only enter a county in one direction (i.e. just the northbound lanes, etc.): CO2, CO112, K-42
The closest a highway comes to entering a county but doesn't?: My nomination of CO150 and Costilla County. 10 ft. per mob-rule map.
Another one for the "near-miss" category: PA 487 does not enter Wyoming County despite being less than 150 feet away at its closest point. This frustrating fact has cost me a clinch of Wyoming County despite a pair of trips to Ricketts Glen via PA 487. And there is nothing nearby that would allow for an easy out-and-back clinch. The nearest state route crossings lead to Tunkhannock, over 20 miles as the crow flies, and 40 miles/50 minutes by road. As such, Wyoming County has become a semi-permanent donut on my county map; a true example of "you have to be going there to go there".

This would potentially be the case for any routes that straddle county lines for their entire length. Orleans County, NY is partially bound by a pair of such routes: NY 272 on the east side and NY 269 on the west.
This leads to the interesting oddity where you could theoretically go south on NY 272, west on NY 104 and north on NY 269 without leaving Orleans County. But by reversing the trip and going south on NY 269 first, then west on NY 104 and north on NY 272, you'd clinch Niagara and Monroe counties as well.

I-70 misses Montgomery County MD by (guessing) about 1/8 of a mile near Mount Airy. There are four counties right in that area (Howard, Carroll, Frederick, Montgomery) although there is not a common point between all 4. I-70 goes through the other three counties listed.
The common road of DE 896 and PA 896 passes through the northeast corner of Cecil County MD for a short distance (1/4 mile at most?). This may be MD 896 but it is NOT signed as such.
Beaver Valley Road, an E-W road east of Brandywine Creek, leaves Delaware, enters Pennsylvania (Delaware County) for a short distance, and then reenters Delaware (topographic reasons, it is following a creek). No signage, but there is a change in pavement. There is (or at least used to be) an 1892 PA -DE border stone on the wooded hill to the south of that road. I haven't been to that stone since about 1990 which is why my language is indefinite about its continued existence.
In the 1990s I walked under the I-84 bridge(s) over the Delaware River to the NY-PA-NJ tristate marker (was able to get there from a cemetery in Port Jervis NY). Assuming that the stone is in the actual tristate location (northenmost point of Sussex County NJ, and of NJ in total), it seemed to me to be less than 50 feet to the eastbound lanes. Maybe 50 feet to a point between the two bridges?

During the Marshalltown, Iowa meet in 2010, we visited the spot on IA 330 where the route clips the corner of a county so briefly that you can get both county line signs in the same photo.
In fact, IA 330 is in Story County for such a short distance that the southbound lanes are in Story County for almost twice as long as the northbound lanes (500 feet southbound, 300 feet northbound).
Other examples in Iowa:US 69 goes through the northwest corner of Worth County for about 1600 feet before entering Minnesota.
IA 39 misses the southeast corner of Ida County by about 500 feet.
I-35 is about 500 feet from Madison County at its closest point.
IA 16 cuts across the northeast corner of Davis County for about 0.8 miles.
IA 15 goes through the northwest corner of Humboldt County for about 1.7 miles before straddling the Palo Alto/Kossuth County line, although IA 15 never fully enters Palo Alto County.
IA 78 runs along the Washington/Jefferson County line for 2.8 miles before shallowly angling into Jefferson County for 1.5 miles.
IA 16 straddles the Henry/Lee County line in the very southwest corner of Henry County for about 0.6 miles but never fully enters Henry County.
The westernmost portion of IA 57 runs along the Franklin/Hardin County line without fully entering either one.
The southernmost portion of IA 25 straddles the Taylor/Ringgold County line without ever fully entering either county. It then passes through the four corners intersection of Adams, Union, Taylor, and Ringgold Counties and straddles the Adams/Union County line without ever fully entering Adams County.
The southernmost portion of IA 17 runs along the Dallas/Polk County line, aside from about 2.6 miles in the middle where it deviates slightly into Polk County, never getting more than 1100 feet from the county line. IA 17 never fully enters Dallas County.
The opposite end of IA 17 has the same situation as IA 25. It straddles the Kossuth/Hancock County line without ever fully entering either one and passes through the four corners intersection of Kossuth, Hancock, Humboldt, and Wright Counties. Then, it straddles the Humboldt/Wright County line without ever fully entering Humboldt County.
There are still several more highways in Iowa that straddle county lines, but I'm going to stop myself there to keep this post from getting excessively long.

US-8 enters into Michigan for 2.3 miles before ending at US-2.
In Georgia, state route 211 barely enters Gwinnett County. State route 347 comes close, but does not enter, Gwinnett County. The intersection of 211 & 347 is in Hall County near Gwinnett, Barrow, Jackson counties (so all three of those count as near miss for 347, and Jackson counts as near miss for 211) .
SR 330 barely enters Clarke County, although there is no signage indicating such. There are a few near-miss routes for Clarke County: SR's 106 and 316 . A lot of people would probably think the east end of 316 is where it is closest to Clarke County, but actually the nearest point would be closer to the US 78/SR 10 interchange.
SR 52 between Gillsville and Maysville runs along the Banks/Jackson and Banks/Hall county lines.
Other Georgia near misses: US 19/SR 400 misses DeKalb and Hall counties, SR 17 misses Oglethorpe County
Other Georgia routes that just enter a county: I-95 enters Effingham County, I-75 enters Cherokee County, I-85 enters Clayton County, SR 138 enters Newton County

Crawford Co, MI
To be clear, I specified Georgia on that post that's being quoted... that part was just removed from the quote
WV 28 passes about 0.2 mile NW of corner of Highland County, VA. This is south of US 33 (Judy Gap) and north of US 250.
At the aforementioned corner, the state line makes a sharp 90 degree turn from generally running north to generally running east.
The continuation of the NB line becomes the county line between Pendleton County, WV and Pocahontas County, WV.
WV 28 also crosses that county line but that crossing is slightly north (on the road) from the closest it gets to the VA county mentioned above.
I remember seeing, and the map confirms, a very small road heading towards that corner of VA. That small road also appears to cross back and forth between WV and VA. Assuming that road is publicly accessible (I don't remember), I did not try to drive that road, due to other experiences I've had on small mountainous WV roads (dirt, with rocks and large boulders).

I-68 in MD at exit 74 (US 40 Scenic / Mountain Road, this is just west of Sideling Hill Cut) comes within about 0.2 mile of PA line (I believe the PA county is Fulton County PA).
I remember that if you come south on Mountain Road, when you enter MD you can see I-68 from there. There are a lot of trees here due to the mountainous terrain.

One that mob-rule is inconclusive about is US 62 and Tillman County, OK. It looks to me like EB 62 straddles the county line, while WB 62 does not enter Tillman County. Anyways I would sure hope that any county-clincher driving that stretch of US 62 would at least swing in past the Headrick historic bridge to make it official.
The jury seems to be perpetually out on the question of US 41 and Monroe County, Florida.

In West Virginia, the southbound side of two-lane US 119 briefly enters Marion County when passing between Monongalia and Taylor counties: https://maps.app.goo.gl/qyD2bsbfRrG9pYqk7. Depending on what imagery you're looking at, the triangle wedge of Marion is either on the shoulder or in the travel lane. I've not seen a definitive answer if the southbound travel lane itself actually enters Marion County or not. Either way, there is no signage mentioning Marion County at this location. There's not any direct road access to the rest of the Marion, either.
Just east of Blacksville, WV 7 grazes the PA state line on a curve. The state line definitely runs through the ROW. When I dug into it previously, it appeared the shoulder entered PA but the travel lanes themselves did not: https://maps.app.goo.gl/3arWR4LZpFQ8vv468
In the I-40 example from the other thread, there are Gray County signs where mob-rule indicates that only part of I-40 actually crosses the line.
Let's see what we have for Utah...
I-80 just misses Rich County, which has its boundary with Summit just north of the railroad track that parallels I-80 to the north. This has actually been the subject of a border dispute in the past, before even any US highways existed - Rich claimed the entire upper Bear River watershed in Utah, which would have put the line on 80 at Wahsatch Hill. Somehow, the railroad was selected as the ultimate boundary.
I-84 is never signed to enter Davis County but unambiguously does for a couple miles on either side of exit 85. Further east, the eastbound lanes spend a good amount of time in Davis, also not signed. Pre-existing US 30S just barely missed Davis, except during the earliest years when it may have followed the Lincoln Highway alignment along what is now SR 60.
US 6 clips the corner of Wasatch County
SR 24 clips the corner of Piute County, where it junctions SR 25
SR 39 winds in and out of Cache County's border with both Weber and Rich numerous times as it follows the county-line watershed divide, though only one crossing of each is signed. It has no road junctions of any significance in Cache.
Exactly one hairpin on SR 92 near the Cascade Springs junction is in Wasatch County
SR 150 just barely enters Wasatch County for a short distance near Upper Provo Falls (not signed) and then barely winds into Duchesne County near Mirror Lake (signed)
SR 248 winds into Wasatch County for a few miles near Jordanelle Reservoir
SR 264 clips the northernmost corner of Emery County

It's Gilmer. Northbound, you get a Gilmer County sign when you first enter and then a Lewis County sign when you leave Gilmer. You can see them both here (Lewis County is way up in the curve).
https://www.google.com/maps/@38.9027703,-80.6133322,3a,53.7y,65.27h,89.25t/data=!3m6!1e1!3m4!1sFWWERkGOVey0PYefrk_fOA!2e0!7i16384!8i8192?entry=ttu
But you actually cross over twice between Braxton and Gilmer as you look at this. Southbound, you actually enter Gilmer County three times. The Braxton County sign is posted when you leave Gilmer the second time (marking the same crossing as the Gilmer County sign in the northbound direction).
If you are driving on I-64 in Virginia between Charlottesville and Richmond, you will see signs that you enter and leave Fluvanna County very quickly. It clips the northern section, but there aren't even any interchanges within the county to access I-64. You have to cross into Louisa or Albemarle County to actually get on or off the interstate.

WV 28 passes about 0.2 mile NW of corner of Highland County, VA. This is south of US 33 (Judy Gap) and north of US 250.
At the aforementioned corner, the state line makes a sharp 90 degree turn from generally running north to generally running east.
The continuation of the NB line becomes the county line between Pendleton County, WV and Pocahontas County, WV.
WV 28 also crosses that county line but that crossing is slightly north (on the road) from the closest it gets to the VA county mentioned above.
I remember seeing, and the map confirms, a very small road heading towards that corner of VA. That small road also appears to cross back and forth between WV and VA. Assuming that road is publicly accessible (I don't remember), I did not try to drive that road, due to other experiences I've had on small mountainous WV roads (dirt, with rocks and large boulders).
It's a U.S. Forest Service road. FR 106 bounces back and forth across the state line for a couple miles heading south, and there is a spur to the Locust Springs Picnic Area in Virginia which is only accessible by car from West Virginia.
I-495 and MA 213 come within feet of the New Hampshire border and therefore Rockingham County.
MN 23 crosses into Douglas County WI for a half mile.

Was looking at this last night on map, this is also the time zone boundary (at this location, New Mexico is Mountain, Texas is Central).
It's always been one of my geek bucket list things to be at a place like that on New Year's Eve at a time when it is one year on one side of the line, and another year on the other side., and walk back and forth between them. But in a way I also feel that if I were to actually do that, it would be a bit hollow, being that time zones, and how we mark the passage of time, are all manmade things (as opposed to things like eclipses, comets, Northern Lights etc.).

It's on US 56 (well) northwest of Amarillo, and due west of (and not very far from) the southwest corner of the Oklahoma panhandle. Where the Texas border makes a 90 degree turn.
My favorite one in Indiana is that I-74 WB enters Rush County, but EB does not.

It could be argued that US 62 and Tillman County is similar, EB enters while WB does not:

One that mob-rule is inconclusive about is US 62 and Tillman County, OK. It looks to me like EB 62 straddles the county line, while WB 62 does not enter Tillman County. Anyways I would sure hope that any county-clincher driving that stretch of US 62 would at least swing in past the Headrick historic bridge to make it official.
On that note, I-490 (NY) straddles the Monroe/Genesee county line for about 2.5 miles. EB is entirely in Genesee County and WB is entirely in Monroe County from just north of Exit 1 to just north of Exit 2. This includes Exit 2 itself, at which
NY 33A crosses the county line in the median of I-490 (https://maps.app.goo.gl/3dgiJMwLtxWKkQQo9).

Two from my driving excursions to New England and beyond in mid '90s.
New Brunswick 289 at Pohenegamook NB -- right near the northernmost point of Maine -- there is a border crossing at Estcourt Station, ME (Aroostook County ME --- note that I do not see this crossing on Googlemaps). I was driving west (heading to Quebec City). I remember a railroad bridge to my left, and if you went under the railroad bridge, customs was just beyond that. According to Wikipedia this border crossing is used by loggers. The Wikipedia entry for Estcourt Station ME is an interesting read -- apparently you can only cross the border there during business hours on weekdays.
Driving south on US 3 in northern New Hampshire - at Stewartstown NH there is a bridge to Beecher Falls, VT (Essex County, VT). US 3 never enters Vermont.
Incidental to the subject of this thread, crossing that bridge looks like you get on VT 259 which goes for less than a mile before it reaches the international border.
Both of these were done on the same trip. For the US 3 case I had come south from Quebec City intentionally to enter the US so I could drive on the northernmost part of US 3.
Forgot that US95 comes within 200' or so of Washington. (So Whitman County, specifically.)
Would US 1 in Middlesex County, Massachusetts count?
It's in Malden for about half a mile and Cambridge for half of a loop ramp as it exits I-93. Used to have more in the county, running across Cambridge, Everett, Malden, and Melrose before being moved to its current freeway/Jersey freeway stretches.

It's also US-64 and US-412. I've taken that way before to bypass both Texas and Kansas on the way to Colorado Springs as I find I-40 and I-70 to be mindnumbing with that as a destination.
I'll tell you, it's so close that I was able to keep feet on the pavement in New Mexico on that shoulder, and manage to piss in Texas without stepping foot in it on that trip.

Just east of Blacksville, WV 7 grazes the PA state line on a curve. The state line definitely runs through the ROW. When I dug into it previously, it appeared the shoulder entered PA but the travel lanes themselves did not: https://maps.app.goo.gl/3arWR4LZpFQ8vv468
I looked on the map and saw that this occurs due to topography as WV 7 is following a creek.
I was not aware of this occurrence. I have explored much of the southern PA border (which is the Mason-Dixon line, with the exception of the Delaware 12-mile circle), but the part I don't know well is where PA meets WV, and especially the part west of I-79 which is where this example is. I'll have to get out there at some point.
Some years ago I did drive out there to drive on US 250 west of I-79 and up to Wheeling, since it passes not far (within a half mile?) of the SW corner of Pennsylvania. I unsuccessfully looked for a marker stone (at SW corner of PA) there near a dirt road there that went east of US 250 (did not have GPS), but did not wander on foot too far off that dirt road since I wasn't sure if I was trespassing. (at the time I did this, I wasn't even sure there was a marker there) Subsequently, I believe I saw a picture of what I was looking for online. It's at least a 250+ mile drive for me one way, so I'm not going to attempt that again unless I have another reason to go out there.

There is a marker at the extreme southwest corner of Pennsylvania. It's on the side of a hill about 800 feet horizontally and a couple hundred feet vertically from the closest road. A friend wrote an article about visiting it last year: https://wvexplorer.com/2022/01/11/storied-west-virginia-monument-stands-forgotten-in-woods/
An abandoned stretch of the original B&O mainline to Wheeling is about 1000 feet west of the corner. Board Tree Tunnel, built in 1851 for the railroad, is also in the vicinity. The B&O took great pains with their alignment in this area because they were not allowed to build in Pennsylvania. This area also has terrain that is unusually rough for northern West Virginia and southwestern Pennsylvania, further complicating matters.
More New York examples:
NY 246 barely enters Genesee County, terminating at NY 63 only a tenth of a mile after crossing the county line.
NY 318 barely enters Ontario County, terminating at NY 14 and the Thruway .7 miles after crossing the county line.
NY 65 clips the northeastern corner of Livingston County for a quarter mile.
NY 263 and NY 266 both barely miss entering Niagara, terminating .3 and .1 miles from the county line, respectively.
NY 383 barely misses entering Livingston County, terminating at NY 36 .7 miles from the county line. Nearby NY 5 misses entering Monroe County by a mile.
NY 438 barely misses entering both Chautauqua and Cattaraugus Counties, terminating at NY 5/US 20 .3 miles from the former and at NY 39/US 62 .7 miles from the latter.
Alright, Nevada. I am going to exclude cases where a state route ends at the county line, such as SRs 705 and 294, as well as cases where there is a close miss/clip in one location and a clear entrance elsewhere:
- I-80 clips Storey County in two separate locations. The Storey-Washoe county line on the north side of Storey follows the centerline of the Truckee River as it existed in the 1950s or earlier. The western spot, unsigned along 80, is just west of Exit 36 and where the Truckee River was realigned during construction of I-80. The eastern spot (signed) is at the northeastern tip of Storey County. Despite I-80 replacing US 40 across Nevada, US 40 did not enter Storey County and was thus a close miss for the entire stretch between Sparks and Fernley while it existed on the surface.
- SR 447 is about 1/4 mile inside Pershing County for several miles between Nixon and Gerlach.
- US 50 comes within about 1 mile of Storey County without entering.
- The south end of SR 338 at the California line misses Mineral County by about 1/3 mile.
- The west end of SR 140 at the Oregon line misses Washoe County by less than 1000 feet. Immediately adjacent, the east end of Oregon SR 140 clips the southwest corner of Harney County, OR.
- SR 206 comes within about 600 feet of Alpine County, California near its southern end, but does not enter nor end at the border.
A weird but similar case is the Churchill-Lyon line running down the median of I-80 for about 3 miles east of Fernley.
Now for California:
- The aforementioned case of I-80 clipping Sierra County near the Nevada border
- US 395 clips Sierra County between the Nevada border and SR 70
- SR 88 follows the Amador - El Dorado county line for several miles between Cook's Station and Kirkwood. These are the only places where SR 88 enters El Dorado County
- SR 4 comes within about a mile of the Tuolumne County line near Cottage Springs
- SR 108 clips the southern tip of Alpine County around Sonora Pass and has a near miss west of Dardanelle, making for both cases on one road. The clip is unsigned.
- SR 128 clips the northwest corner of Solano County
- I-80 clips the southern tip of Napa County, unsigned.
- SR 108 comes within 200 feet of San Joaquin County in Riverbank
- SR 129 comes within 200 feet of Monterey County east of Watsonville
- SR 198 comes within 200 feet of San Benito County
- SR 91 comes within 500 feet of the southern tip of San Bernardino County
- SR 99 comes within 1/2 mile of Kings County and within 1000 feet of Yolo County
- US 395 comes within 1 mile of Plumas County south of Susanville
The one I am aware of in Nebraska is that US 34 and NE 2 enter Merrick County southeast of Grand Island. I believe the amount of distance you are in Merrick County is the length of the bridge over the Platte River there.

This county highway isn't even
on the county line, which follows Honeoye Creek. The county line sign is just erroneously placed a few hundred feet too soon (which is somewhat common when a body of water forms the county line, but normally it would be closer to the start of the bridge).

NOTE - I redid this post so quoted material would appear as such. I will say the same things, but my exact wording may differ.
If the southwest corner marker is that far away from the nearest road, I was not that close to it, as I did not venture that far off "what I believe" was the nearest road -- which I thought was the following: I took a somewhat windy dirt road east from US 250 almost due west of where my topo maps said the state corner was, and then kept track of the curves as I drove -- matching them to the map, and stopped in a location where the map seemed to indicate I was closest to the southwest corner. This technique has worked for me in the past (e.g., when I went to PA/MD/WV tristate marker -- but that was in a much more open area and there may have been either a power line ROW, or underground gas line ROW (or maybe both), anyway my point is that the tristate marker could be seen from a distance, which is different than a wooded hilly area -- although snow cover and the resulting color contrast majorly helps in a case like this (as I see in the linked article). I did this when there was no snow on the ground).
I am glad I was not all that close, it would bother me a lot more if I was "that close" and didn't see it. The linked material indicates that it sits on private land, and I personally did not want to risk getting arrested, being 250 miles away from home on a day trip, so I am also glad I trusted my "gut feeling" about whether to proceed.
At Indiana SR 662's western endpoint, it's hard to tell if it enters Vanderburgh County. The county line passes through the interchange with I-69, but INDOT sometimes has routes end at jurisdictional boundaries.
The signage (https://maps.app.goo.gl/Ge49h3SaRUPaGX8v7) shows the route ending before the county line, but the INDOT route inventory and GIS maps say it goes all the way to the intersection with the ramps to SB I-69.
If we're counting former counties, I-95 barely enters DC on the Woodrow Wilson Bridge between Alexandria, VA and Oxon Hill, MD.

For 40+ years, I have always wanted to go to Cairo Illinois (which is Alexander County, IL), to see the mile where US 60 is in IL.
Always fascinated me because I believe IL is the only state with five US x0 routes, and I've already seen 20, 30, 40, and 50 there.
I know this occurs due to US 20 diving south due to Lake Erie being the international border, and having to get under Lake Michigan. Indiana and Ohio only have 4 US x0 routes since US 60 stays south of the Ohio River other than at Cairo.
Once upon a time, California had five x0 US routes ... of course I-80, 10, and 8 killed four of them.
According to NYSDOT Reference Markers, NY Route 8 briefly touches Otsego County at this point between New Berlin and South New Berlin, New York. There are no county line markers, and no references to segment #4 of SR 8, but the segment sequencing jumps on the references markers from segment #3 (Chenango County) to #5 (Chenango County), leaving one to assume #4 is a brief blip into Otsego County.

There are no county line markers, and no references to segment #4 of SR 8, but the segment sequencing jumps on the references markers from segment #3 (Chenango County) to #5 (Chenango County), leaving one to assume #4 is a brief blip into Otsego County.

Meh. Someone could check the sufficiency manual...
As discussed before I-75 clips Crawford County, Georgia (not Michigan) so much to the fact that on mob-rule I didn't have the county counted even though I've been through there on I-75 several times.

And not too far away, MA 114A barely enters RI at BOTH ends.
Mentioned many times before by others, but the US-58 Bypass skirts along the North Carolina border as its wraps around the south side of Danville, Virginia. At its closest, the eastbound travel lanes are about 220 feet away from the Caswell County border. All four of the eastbound ramps at the US-29 interchange enter Caswell County, as does the lefthand exit ramp from the westbound lanes.

Was gonna argue that GA 97 just barely enters Florida as well, but double checking Google Maps the road is signed as CR 269A. There are GA 97 trailblazers on US 90, however.

US 31 also gets within about 1,000 feet of the northwest corner of Florida near Atmore, AL.
Al 54 gets within about 500 feet of the Florida State Line just east of Florala, AL.
AL 53 runs right along the Alabama/Tennessee State Line in Ardmore, AL/TN for a ways.
Southern California:
I-5 barely misses Ventura County going over the Grapevine (by about 2.5 mi)
CA-33 passes through Santa Barbara County with no intersections for about 6 mi
I-605 kisses Orange County when it reaches Seal Beach (it ends at I-405 right after)
CA-22 similarly barely hits Long Beach (Los Angeles County) after the I-605/I-405 junction
CA-72 goes through Orange County for about 2,000 feet before its terminus at CA-39
CA-91 barely misses the San Bernardino County Line right before the Green River Rd exit
CA-166 rides the Santa Barbara-San Luis Obispo County Line, going back and forth between counties (is this considered Central California?)

Longer than most of these but 90 in McHenry Illinois and 80 in Kendall . These are both big counties one over 100k and the other over 200.
McHenry only recently got an interchange.
Also both disprove roads drive growth. In both cases not just the Interstate but the state arterial were 2 lane roads.

You do realize that both ends of MA/RI 114A are in RI, right? I'd hardly call that the

I was thinking opposite in terms of I-490 spending its whole length in one county and entering two different counties at each end
vs. MA 114A spending its length in potentially multiple counties and entering the same county at each end. But I didn't realize how short it was, so "multiple counties" in MA doesn't hold up.

Officially, it ends at the state line, so it doesn't (although Google Maps had it doing so erroneously).
Speaking of RI and CT, RI 78 barely enters CT (although it was once planned to extend to I-95).

AL 53 runs right along the Alabama/Tennessee State Line in Ardmore, AL/TN for a ways.
I've wondered about this, since there are Tennessee mile markers along the state line portion of AL 53 for TN 7 at Lewter's Chapel Road (https://www.google.com/maps/@34.9919269,-86.8362401,3a,42.5y,278.27h,88.42t/data=!3m6!1e1!3m4!1sVdhgGxzxGkKe6zuXecZNSA!2e0!7i16384!8i8192?entry=ttu). Alabama 53 then turns south on Old US 31 (AL 251) before the railway crossing, and continues west to its terminus at Interstate 65.

There's a similar highway in NY 120A that runs along the CT border at times
WV-12 ends in Peterstown (Monroe County) about 500 feet from the Virginia border (ergo, Giles County). Unless you follow the main road (US-219), which takes a little bit longer (about 600 feet). Of course, WV-12 used to follow the route of US-219 into Virginia and back over into Mercer County, West Virginia. (Which is only about 4-1/4 miles away on the other side of Glen Lyn as the crow flies, and not much further by road).
Here's a different twist: VA-107 is entirely in Smythe County, running parallel to the Washington County line for its entire length of about 8.4 miles. At its closest, it is about 4,250 feet away from the border, and at its furthest, it is only about 1.5 miles away. The border isn't perfectly straight, but "close enough for government work".

Here's an example of such a thing on an Interstate in Georgia: https://maps.app.goo.gl/CyYQsRox9X1F56W99
I-75 enters Crawford County for a short distance, but the county lines either way are fully signposted.
Just to the east, US 41 and GA 11 historically served as part of the border between Peach and Houston counties (since Peach County was split off from Houston, Crawford, and Macon counties so Fort Valley could be a county seat, at the tail end of the period of county creation mania in Georgia inspired by the County Unit System). However, a few years ago GDOT realigned the GA 49 intersection to make it the through route and now US 41 and GA 11 now are fully inside Peach County for a few hundred feet. https://www.openstreetmap.org/#map=16/32.6742/-83.7058
Not exactly the same thing but there's a weird zig-zag in the Crawford–Peach boundary that leads to GA 96 and GA 540 entering, leaving, and then reentering Peach County again over the course of a mile, presumably because some farmer wanted to keep all their land in Crawford County back when the boundary was drawn. https://www.openstreetmap.org/#map=15/32.5611/-83.9570
I-95 has a short stretch in Effingham County (Ga.) between Chatham County and the South Carolina state line, with no interchange. https://www.openstreetmap.org/#map=14/32.2404/-81.1588
GA 111 almost makes it to US 27 in Gadsden County, Florida, but misses by a few hundred feet (and also misses entering Decatur County, Ga. by about the same amount). https://www.openstreetmap.org/#map=16/30.6892/-84.3779 Within Florida itself, it isn't signed as anything, not even as a county highway or with a posted street name. It gets a To trailblazer from US 27 at least. https://maps.app.goo.gl/iMpv2VQiEMK7oB499 On a closely related note, it also seems that US 27 and GA 1 miss entering Grady County, Ga. by a hair.
US-460 in Campbell County, Virginia gets within 110 feet of Amherst County as the original James River border along the south side of Feagans Island ventures inward away from this narrow channel. I usually wouldn't include a river border in this list, but this seems like a worthy exception. Getting even closer, the former Chesapeake and Ohio mainline of CSX (100-foot right-of-way) squeezes through in between US-460 and Amherst County.
^^^
Similarly, US-1 in Marston, Richmond County, North Carolina, skirts the western edge of Scotland County by about 200 feet. No river this time, but another part of CSX (the former Seaboard Coast Line mainline) sneaks in between. Bonus: The parallel road on the east side of tracks (Kid Road) actually skips into Scotland County for about 115 feet.
NC-151 is listed as entirely in Buncombe County, but the southernmost tip sneaks into Henderson County just as it reaches the Blue Ridge Parkway. About 25 feet, give or take.

Another one for the "near-miss" category: PA 487 does not enter Wyoming County despite being less than 150 feet away at its closest point. This frustrating fact has cost me a clinch of Wyoming County despite a pair of trips to Ricketts Glen via PA 487. And there is nothing nearby that would allow for an easy out-and-back clinch. The nearest state route crossings lead to Tunkhannock, over 20 miles as the crow flies, and 40 miles/50 minutes by road. As such, Wyoming County has become a semi-permanent donut on my county map; a true example of "you have to be going there to go there".
As part of a proposed county-clinching trip, my plan for getting my friend Wyoming County was to out-and-back 150 feet on the dirt road that runs east from PA 487 at the place the route approaches the county line. That plan assumed good weather; the dirt road is on a slope, so I would not want to take my car on that slope if the road is muddy or snow-covered.

I-95 in Darlington County, SC
I-95 also passes through the southern tip of Marlboro County, South Carolina, for about 1000 feet at the Great Pee Dee River. This fact is not mentioned on I-95. In fact, the Welcome to Florence County sign (https://maps.app.goo.gl/uavrtA1RcXMurV9c8) ahead of the bridge across the Great Pee Dee River swamp on southbound I-95 is within feet of the Dillon–Marlboro county line.
Lunenburg County, Virginia, is surprisingly difficult to clinch. The southbound lanes of I-85 come within 350 feet of the Lunenburg–Brunswick–Mecklenburg tripoint just west of the Meherrin River, and US 15 comes within 4000 feet of the western border at Keysville in Charlotte County. I finally clinched Lunenburg County on US 360, which enters the county in 1 3/4 places. The westbound lanes of US 360 run atop the Prince Edward–Lunenburg county line at Virso, and the entire U.S. Highway enters Lunenburg County for 1000 feet at Meherrin.
On the same US 15 trip in which I missed Lunenburg County, I missed Cumberland County. US 15 passes 1,500 feet to the west of the Cumberland–Prince Edward–Buckingham tripoint at the Appomattox River. I clinched Cumberland County years later by taking VA 13 just over the Powhatan County line from Tobaccoville.
QC 247's southbound lanes enter Orleans County, Vermont.
US 378 just barely clips Williamsburg County, SC west of Lake City. It wasn't signed the last time I was there.
Where I-75 briefly crosses into Crawford County, GA, it is signed in both directions.
I-40 barely clips Carroll County, Tennessee, and it is signed at least westbound.
I-95 comes within a mile of Beaufort County, SC. It is definitely the largest county in SC by population without direct interstate access.
I-195 near BWI Airport just misses Howard County where it crosses the Anne Arundel/Baltimore county line at the Patapsco River. The Anne Arundel/Baltimore/Howard county tripoint is just upstream where Deep Run empties into the Patapsco (https://www.google.com/maps/@39.2134089,-76.6969087,18.25z/data=!5m1!1e1?entry=ttu).

I-70 misses Montgomery County MD by (guessing) about 1/8 of a mile near Mount Airy. There are four counties right in that area (Howard, Carroll, Frederick, Montgomery) although there is not a common point between all 4. I-70 goes through the other three counties listed.
Building off this one:
-I-70 & US 40, in addition to missing Montgomery County, clip Carroll County for about a mile while otherwise passing between longer lengths in Frederick & Howard counties on either side. This mile is the only interstate or US route to enter Carroll County anywhere - it's only served by state routes otherwise. This would put Carroll County as the most populated MD county only served by state routes if not for this mile of I-70/US 40, so instead that honor goes to St. Mary's County.
-I think there is actually a quadpoint where Carroll, Frederick, Howard & Montgomery counties all meet - IIRC, it's Parr's Spring (the source of the South Branch Patapsco River) just south of I-70 exit 68 (https://www.google.com/maps/@39.3567121,-77.1657194,17z/data=!5m1!1e1?entry=ttu).
-MD 27 does several clips in the same area because of that quadpoint - it's primarily in Montgomery County to the south & Carroll County to the north, but in between it clips Howard County for about a mile after crossing the Patuxent River close to its source, then crosses the sliver of Montgomery County extending to that quadpoint (https://www.google.com/maps/place/Montgomery+County,+MD/@39.3448897,-77.1770178,2986m/data=!3m1!1e3!4m6!3m5!1s0x89b6323583b8a387:0x780b190677a96873!8m2!3d39.1547426!4d-77.2405153!16zL20vMGJ4OXk!5m1!1e1?entry=ttu), and finally clips Frederick County for about a half-mile with the Frederick/Carroll county line briefly following MD 27 thru the I-70/US 40 interchange.
-I-95 also just misses Montgomery County, as I-495 reaches the Montgomery/Prince George's County line about a mile west of where I-95 branches off the beltway. This leaves Montgomery County as only being served by 3di's (I-270, I-370, I-495) despite being the most populous MD county.

Very true, Lunenburg County, VA has eluded me for this reason - for decades. Grew up in VA but since moved away and Lunenburg County is a hole in my travels through the Old Dominion.
On the opposite end is Fluvanna County, a corner of which hosts less than one mile of I-64. Looking at an average scale state map, you can't tell if 64 enters the county or not but yes, it does. And VDOT signage at each boundary too, looking redundant - thought it is not.

I misspoke then, if all four counties do meet there. I do know that Montgomery County approaches that spring from the west in a very narrow sliver which crosses Rt. 27 (also mentioned by jmacswimmer, who I am quoting).
That stretch of Rt. 27 is about a 20 mile bike ride from where I live (therefore a 40+ mile round trip). I have made that bike ride several times for the four county thing. It's also several hundred feet higher in elevation so in addition to the distance, it's also quite a workout for me (at 55+). There is a small road in that area that is called "Four County Road" or something similar (has a rectangular green sign with the name of the road). IIRC it is to the southwest of the I-70/MD 27 interchange, and north of the gas stations on the west side of MD 27 there. EDIT - on the map that jwacswimmer provides in his post, it is the road that goes to H&H Concrete Construction.

Being local, and a bike rider with a need to know the local roads, I have similar (but more detailed) map at home that I would like to check (but I'm not there right now).
I'll have to report back later. However, the map that kphoger shows does present the narrow wedge of Montgomery County that narrows as it goes east, and looks a lot like I remember from my maps. I just don't remember if the top part of the MontCo triangle reaches that spring.
EDIT -- but several links (one in jmacswimmer's post) claim that it does, including an article from the Baltimore Sun.
To refer back to my elevation comment, where I live is about 400 foot elevation, and the area shown here is about 800 foot elevation. You can see from the surrounding area on kphogers topo map that it is not flat here (although it is not Sideling Hill steep either), but it is rolling enough to be demanding on one's knees.
Another interesting thing shown by that topo map is that the Four County Drive I mentioned (SW of the interchange) earlier appears to only be in Frederick County.

But isn't this an oddity: MD-144 (the rerouted section of the original National Road) misses Montgomery County by about 260 feet; misses Howard County by about 305 feet; and crosses into Frederick County for about 365 feet before dropping off of the map. Only one of these actually qualifies for this thread, however, as this section of MD-144 jumps back into Howard County about 2 miles east of here and another segment of MD-144 in Frederick County starts back up about 5 miles west of here.

Being local, and a bike rider with a need to know the local roads, I have similar (but more detailed) map at home that I would like to check (but I'm not there right now).
I'll have to report back later. However, the map that kphoger shows does present the narrow wedge of Montgomery County that narrows as it goes east, and looks a lot like I remember from my maps. I just don't remember if the top part of the MontCo triangle reaches that spring.
EDIT -- but several links (one in jmacswimmer's post) claim that it does, including an article from the Baltimore Sun.

I have ADC street maps of all of the involved counties.
I also have a DeLorme map of the entire state.
Every one of them shows a quad point, on the ADC maps it is generally on the west side of the lake.
Drawing a circle around this point, Carroll County is (generally) to the north, Howard County is (generally) to the S and SE, Montgomery County is a point (at approximately 7:30 (which is SW)), and Frederick County is (generally) from SW to due W. The Carroll County-Frederick County line goes NW from the lake to Rt. 27 and then follows Rt. 27 north towards I-70.
You can't legally go there though (I tried once from Rt 144, east of Rt 27), signs say private property, and I did not trespass.
The other thing I learned from this exercise which I never really realized is that the Patuxent River, which forms almost all of the Howard County-Montgomery County border, begins west of Rt 27 about 3/4 to 1 mile southwest of Parr's Spring (the quadpoint), which is where the Patapsco River begins.

Someone needs to go out there and find the survey markers.

^^ I thought the west end of Texas was in Mountain time.
El Paso County , Hudspeth County , and parts of Culberson County are on Mountain Time.
THe farthest point east on mountain time in Texas is over 100 miles west of The west boundary of the panhandle and 300 miles south.

Here's the Baltimore Sun article I mentioned (from 2000).

My trespassing days are over. This article is good enough for me.
-CA 99 barely misses Kings County, California. Closest approach is around Exit 109 (about 111 miles north of the bottom of the Grapevine Grade), which serves Avenue 384.
How could I forget WI 57 barely enters Kewanee County on the way to Door County.

It isn't just a 'tick' of the corner, it is longer than that. There is a gas station on WI 57 there that has had problems with the regulators (especially in the 1980s and 1990s) because Kewanee County is/was considered to be in a 'non-attainment area' for some pollutants and and thus subjected to the same more expensive seasonal reformulated fuel rules that apply further south along the Lake Michigan lake shore (ie, in the Milwaukee, Racine and Kenosha areas, as well as in Chicagoland), while if they were literally next door in Brown or Door Counties, they wouldn't be subject to those rules. I haven't heard anything about them since.

Backing up Montgomery County's claim is that Lakeview Drive off MD 144 where it turns northward is considered to be within three counties (Frederick, Montgomery and Howard).
We can debate if this is "barely" but it was always of great interest to me, being a native Delawarean.
US 50 passes within a mile (as the crow flies) from the SW corner of Delaware (Sussex County). I passed through this area yesterday on a business trip, and got off US 50 to go to the Mason-Dixon monument there (at SW corner of Delaware). By road it it a little less than a mile as well.
This was the first time I had visited this location in about 34 years.
Some Texas examples, with a Google Maps link to the location with the county highlighted:
US-281 passes through Coryell County for only 2.2 miles, in and around Evant. South of this area is Lampasas County and north of it is Hamilton County - https://www.google.com/maps/place/Coryell+County,+TX/@31.4647837,-98.1694204,13.7z/data=!4m6!3m5!1s0x865aea79502a7747:0xd8f2d01ca81207cf!8m2!3d31.4774358!4d-97.87216!16zL20vMG1zNDk?hl=en&entry=ttu (https://www.google.com/maps/place/Coryell+County,+TX/@31.4647837,-98.1694204,13.7z/data=!4m6!3m5!1s0x865aea79502a7747:0xd8f2d01ca81207cf!8m2!3d31.4774358!4d-97.87216!16zL20vMG1zNDk?hl=en&entry=ttu)
FM-1389 barely passes through Dallas County for only 0.2 miles in Combine. The rest of the road is in Kaufman County. If you look at the satellite view, you'll see there are several houses that are near the county line but almost all of them are entirely on the Kaufman County side, while the Dallas County side is largely undeveloped. This is because the school district line follows the county line (which isn't as common as you may think given the ISD system in place), with the Kaufman County side being in Crandall ISD and the Dallas County side being in Dallas ISD and zoned to Seagoville schools. Crandall schools are much better (no bias from me even as a Crandall alum :-D), so that side is much more popular to build on. - https://www.google.com/maps/place/Dallas+County,+TX/@32.6043968,-96.5246887,16z/data=!4m6!3m5!1s0x864ebf4a52bd4381:0x47b199369cddd987!8m2!3d32.8024682!4d-96.8350999!16zL20vMG1zMW4?entry=ttu (https://www.google.com/maps/place/Dallas+County,+TX/@32.6043968,-96.5246887,16z/data=!4m6!3m5!1s0x864ebf4a52bd4381:0x47b199369cddd987!8m2!3d32.8024682!4d-96.8350999!16zL20vMG1zMW4?entry=ttu)
A few more examples from NY (this happens quite a lot, at least in the Southern Tier):
- NY 83 is literally a railroad crossing away from Cattaraugus County: https://maps.app.goo.gl/mvS8f4yg5q4RNemj6
- NY 79 enters Chenango County for about 0.4 miles: https://maps.app.goo.gl/nFSVduwfL5rLV2uw8
- I-88 enters a brief jut-out of Otego County for a total of 0.2 miles (though it properly re-enters Otego County several later, so this might not count): https://maps.app.goo.gl/jepmdm3t9nkgHnJAA
- NY 34 enters Chemung County for only 4.5 miles
- NY 224 misses Tompkins County by about 0.4 miles: https://maps.app.goo.gl/zkJqnRCdY4UrTuDT8
- NY 228 terminates 0.1 miles from the Tompkins County border: https://maps.app.goo.gl/12fog8nAjSXZ3NjR6
- NY 414 gets about 4.2 miles within Chemung County: https://maps.app.goo.gl/35BfU5qTbf8mPQvVA
- NY 36 comes within 0.3 miles of Allegheny County (likewise, NY 70 terminates in Steuben County 0.3 miles after entering): https://maps.app.goo.gl/qY45AuGLGdtGXzqu9
- NY 39 enters Cattaraugus County for 1.0 mile (https://maps.app.goo.gl/RvvvdxSbqeJNKhz8A), and spends about 5 more miles just north of the county (coming as close as 225 ft), before re-entering some 20 miles further west
- I-90 comes within 2.2 miles of Cattaraugus County
- NY 438 comes as close as 370 ft of Chautauqua County
- NY 31 enters Seneca County for only 1.7 miles: https://maps.app.goo.gl/tJYFWK3rcfyrnJFGA
- Another NY 21 example, where it misses Livingston County by 0.4 miles just east of Wayland
- NY 19A misses Livingston County by about 255 ft
- NY 13 enters Schuyler County for 2.5 miles: https://maps.app.goo.gl/1xEKkLbjKcxvuisb9
- NY 226 terminates just 0.2 miles from Yates County: https://maps.app.goo.gl/wWqKwFKAVqHKGrDN7
I believe I mentioned both of these before, but in separate posts. I'm repeating them here, you'll see why.
US 50 passes within a mile of the southwest corner of Delaware (Sussex County) -- while always staying in Maryland.
US 250 passes within a mile of the southwest corner of Pennsylvania (Greene County) -- while always stauing in West Virginia.
I just belatedly noticed that the two mentioned roads are a parent/child pair, where both do a similar thing.
===========================
And US 220 used to just barely enter Tioga County NY (Waverly, at NY-17/I-86 interchange) -- but I haven't been through there in 20+ years, assume it is still the same. I'm sure this was mentioned earlier, but I can't spare the time to look right now.
