Highways that BARELY enter or miss a county

[cockroachking]

NY 65 clips the northeastern corner of Livingston County for a quarter mile.

So it does. I did not know that previously. It even passes less than 200 feet from the Monroe/Ontario/Livingston county tri-point.

And how about this rare pairing of one county's county line sign with another county's CR shield?

Ok, how about a concurrency between two county routes from two different counties? Chenango CR-14 and Madison CR-73 have that covered. They both run along the county line before splitting a bit further west.

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

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.

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 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.

(Washington City used to be in Washington County, District of Columbia)

NY 83 barely misses Cattaraugus County.

[tmoore952]

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.

[US 89]

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.

Some maps show that US 460 just barely clips Surry County, VA between Sussex and Southampton counties. If it does, it isn't signed. If it doesn't, it barely misses it.

[TheHighwayMan3561]

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.

Another brand new entry: with TH 96 being eliminated east of TH 244 in Dellwood, 96 has about 300 feet in Washington County.

Meh.  Someone could check the sufficiency manual...

[Flint1979]

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.

RI 15 barely enters MA (does this count?)

RI 15 barely enters MA (does this count?)

And not too far away, MA 114A barely enters RI at BOTH ends. 

[Dirt Roads]

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.

RI 15 barely enters MA (does this count?)

And not too far away, MA 114A barely enters RI at BOTH ends. 

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?)

RI 15 barely enters MA (does this count?)

And not too far away, MA 114A barely enters RI at BOTH ends.

I-490 (NY) is just the opposite. Almost its entire length is in Monroe County but it enters Genesee and Ontario counties near its respective western and eastern termini at I-90.

[TheRhodeGeek]

RI 15 barely enters MA (does this count?)

And not too far away, MA 114A barely enters RI at BOTH ends.

Also MA 31 barely enters CT (just like other examples it technically starts there and it is [according to google maps] signed as CT 31 on CT 197 using a CT highway shield even though there already is a state highway named CT 31)

[3467]

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 opposite of the I-490 situation.

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. Alabama 53 then turns south on Old US 31 (AL 251) before the railway crossing, and continues west to its terminus at Interstate 65.



This situation seems similar to the dual maintenance seen along Missouri 43 / Oklahoma 20. Maybe an email to the DOTs will answer it...

There's a similar highway in NY 120A that runs along the CT border at times
