What counties do you know of that have no 4-way intersections or freeway interchanges where each leg is at least a state route? We've had a thread on counties without traffic lights (https://www.aaroads.com/forum/index.php?topic=8364.0), so I'm curious how that list compares to this one.
I'll start with Utah: Beaver, Daggett, Duchesne, Garfield, Kane, Rich, Tooele, Uintah, Wasatch, Washington, and Wayne County do not have any 4-way state highway junctions, which is a lot more than the 6 Utah counties without a traffic light.
Pretty sure none of the State Highway junctions in Alpine County, CA is four way.
I believe Hamilton County, NY qualifies (correct me if I'm wrong). There are a number of state route junctions, but they're all three-way.
It's unlikely that any other NY counties qualify - pretty well every county besides Hamilton has one or more population centers with a bunch of state routes.
Counties in Virginia that meet this criteria:
Bath
Buchanan
Craig
Cumberland
Dickenson
Essex
Fluvanna
Giles
Goochland
King and Queen
Lee
Lunenburg
Madison
Mathews
Middlesex
Northumberland
Powhatan
Russell
Scott
Surry
Westmoreland
Also the Independent Cities of Manassas Park and Radford
Kalawao in Hawaii :bigass:
Coos County OR has three way intersections with a state route involved but no 4-way intersections as defined by the OP.
Rick
Menominee County, WI
Florence County, WI
Vilas County, WI
Probably several counties in upper MI as well. St Louis County, MN has only one, and that's a county of 200k people.
In the UP of Michigan:
- Alger
- Baraga
- Delta
- Dickinson
- Keweenaw
- Iron
- Marquette
- Menominee
- Schoolcraft
Houghton is an edge case. There is a four-way intersection with US 41 and M-203. The southern leg is US 41 southbound, the eastern leg is US 41 northbound, the northern leg has both directions of US 41, and the western leg is M-203. All other highway intersections in the county are three-way (or the fourth leg is not a state highway).
Pulaski and Hardin Counties in Southern Illinois qualify, I think...

Much of this is due to the propensity of highways to join each other for a short distance. For example, an E-W route might meet a N-S route, travel concurrently with it for a few miles (or even as little as a few blocks, as in the case of Jonesville in Hillsdale County) and then strike off on it's own again. This results in 2 intersections with 3-way connections, but no 4-way connection.
Alaska
Yes, I know it's a state, but there are no freaking 4-way state highway intersections in the entire state, so all boroughs qualify for this thread.
Definitely not Lee County, Ky. We have no four-way state highway intersections. All of our bordering counties, however, do have four-way intersections.

If I'm understanding the question right then just off the top of my head Sanillac County shouldn't be on the list. M-53 and M-46 intersect in the western part of the county and have all four directions as a state highway.

While it won't qualify due to highway junctions, amazingly enough from what I can tell Salem County, NJ has no 4 way state or US route surface intersections.
NJ 140 and 48 T's at US 130 and both end at US 40. NJ 45 and NJ 77 both end at NJ 49. NJ 45 runs concurrent with US 40 for a little bit so that won't qualify. And while NJ 77 and US 40 meet, it's actually at a 5 way traffic circle including a county road, not a 4 way intersection, so it doesn't meet the qualifications here either!
Oregon has several, in addition to Coos County mentioned above:
Curry County
Lake County
Columbia County
Wheeler County
Grant County
Lincoln County
Clatsop County
Hood River County
Wallowa County
Del Norte County CA is another one.
Missouri: (this list will be expanded, supplementary/Lettered Routes excluded)

... so it would qualify, then.
In Texas, my first thought was Terrell and Jeff Davis. Of course, there's also Kenedy, which doesn't even have a second highway to intersect with US 77. Checking a map, I also found Edwards and Kent. I thought Mills was a good candidate, because none of the seven highways in Goldthwaite meet at a four-way, but there's one between two minor highways at the edge of the county.

Sorry, my mistake. Not the first time, and most likely won't be the last. :spin:
Predictably, almost all of Indiana's are in the southern (less flat) part of the state. There are a few that get by on the technicality of two highways intersecting but being concurrent for a short distance so there is no intersection where all four directions are highways. Also a few that are recent due to routes being decommissioned in cities:
Brown

Franklin

Three in St. Louis County. The OP's definition includes interchanges.
There's only one county in Vermont that meets the OP's criteria: Grand Isle.
Stark County, IL came to mind. Every junction is either the start or end of a multiplex, or a T-intersection in the case of IL-91/93. I'll also add Wabash, Edwards, and Calhoun County in Illinois to the list.
MN list: it has a lot more than you'd think because of the funny little "hop duplexes" it has
Lake (only state highway junction is MN 1/MN 61; only other state route in the county is a sliver of MN 169)
Cook (only one state route)
Koochiching (became the case when MN 332 was decommissioned)
Houston
Lake of the Woods
Ottawa County MI went from having a 4-way to not having one and then back to having one.
Previously there was a 4-way connection at US-31 with Bus I-196. However, when the business routes in Holland were turned back to city control, that intersection became a 3-way connection.
Then M-231 was created, which has a 4-way connection at M-104. So Ottawa is again off the list.
Florida
Monroe, Glades, Franklin, Gulf, Hendry*
Alabama
Russell and Perry are the only two, as far as I can tell.
* If you want to be precise, there's also no four-way state-maintained intersections; but SR 29 makes a slight 330-foot jog/concurrency from Main Street to Bridge Street via SR 80 in La Belle, to continue north.
Here's a weird one: Jo Daviess County, IL.
IL-35 meets US20 and ends there at an interchange. However, the interchange has no 4-way intersections (https://www.google.com/maps/@42.4903606,-90.6443564,16.29z/data=!5m1!1e1).
Also: Christian County, IL. IL-29 and IL-48 cross over each other via overpass, but are connected by a short access road. Does that short access road count as an interchange? Christian County has no other 4-way junctions.
Other counties in IL that qualify: Hancock, Brown, Shelby, Clay, Pulaski. Moultrie almost qualifies but there's a 4-way junction along its northern county line.

Scratch Montcalm off! Montcalm County has not one, but two four-way state highway intersections (M-57/M-91 in Greenville and M-57/M-66 near Sheridan).
Hillsdale is an odd case, as the (four-way) US-127/M-34 intersection is on the Lenawee/Hillsdale county line.
Correct on Montcalm. I don't know how I missed seeing those.
Yeah, Hillsdale is a maybe. I was so excited about finding a jog in Jonesville that I missed the 4-way on the county line. I suppose it depends on exactly where the road is vs the survey line. Technically, only 3 of the 4 legs are in Hillsdale.
Here's what I got for Washington:
- Whatcom
- San Juan (in fact, no state highways at all other than ferry docks!)

^ My review excluded state-maintained roadways lower than state highway status, particularly frontage roads. If frontage roads were included, this county would not have been listed.

I wouldn't count 127 and 34 since one leg is in lenawee county, one is in Hillsdale county and the other two legs are the county line. I can't find any in Hillsdale county. All the highways that cross another highway take a jog in the route.
I haven't looked over all of Iowa, but Winnebago and Mitchell Counties each have 2 highways where they overlap.

Surprisingly quite a few in Iowa, and many more where there's only one.
Iowa: Lyon*, Clay, Palo Alto, Hancock*, Winnebago, Mitchell, Allamakee, Butler*, Wright, Ida*, Crawford*, Iowa, Cedar*, Louisa, Henry, Van Buren, Davis, Union, Ringgold, Taylor, Page.
Previously: Calhoun and Sac, both before 2012 and relocated four-lane US 20; Jefferson, before 2008; Wapello, before 2007
*These counties have T's where one route moves over a mile (or in Crawford's and Taylor's cases, less). The rest have T's and/or longer duplexes.

Surprisingly, I think Deschutes County counts as well. US-97 and US-20 is a complicated matter, as there are 2 separate freeway interchanges between the highways, but neither of them feel like "4 way" since they are partial interchanges. And if you want to go off the business loop instead (old US-97), then it's two 3-way intersections with a multiplex in between. I don't know how to qualify it overall.
US-97 and OR-126 in Redmond are two separate 3 way intersections, with a short multiplex.
OR-126 and US-20 are a 3 way intersection in Sisters and are mutliplexed all the way up Santiam Pass.
Every other highway ends at its intersection with another one: eg. OR-31, OR-370, OR-242
Modoc County, CA has none.

You forgot Door County the most obvious one. They have 2 state routs WI-42 and WI-57 they do intersect twice but never 4 way.

Kalawao in Hawaii :bigass:
Speaking of counties in Hawaii that actually have state highways, there should be three of them that don't have any 4-way state highway intersections:
Honolulu
Kauai
Hawaii
Three CA counties featuring zero 4-way SH intersections (or interchanges, for that matter) are Lake, Mendocino, and Trinity. Humboldt would have joined that list except for a couple of instances where the US 101 freeway crosses its original alignment, now CA 254 -- which was retained in the state system to provide a scenic alternative through the area's redwood groves between Garberville and Pepperwood.

If you consider Interstates as "state routes" (since they're maintained by the respective states), there are a number on Oahu. Even not counting Interstates, there's the HI 76/HI 7101/HI 7110 interchange just south of I-H1.

HI 11/HI 2000 in Hilo. 2000 does extend east of 11.

Here's what I got for Washington:
I'm going to have to disagree with Skagit. SR 20 and I-5 meet at an Interchange in Burlington, and all 4 directions are highways.
So do interstates and US routes count?
We are getting some examples that *technically* qualify because the only 4-way intersections between numbered routes involve an interstate or US route.
However, I think that defies the spirit of the thread. Instead, we could just assume for the purposes of this thread that we've already done a thread about counties with no 4-way interstate and US route intersections, and eliminated such counties from contention.
(Or someone could start such a thread to give us a basis for that assumption :))

Actually, since Interstates and US highways are invariably the property of the state's DOT, it could be considered that
all roads under state jurisdiction are state highways, regardless of posted signage. That's definitely the case here in CA; which, if interchanges with four distinct state-owned legs are included, disqualifies a significant number of counties from the list.

What counties do you know of that have no 4-way intersections or freeway interchanges where each leg is at least a state route?

HI 11/HI 2000 in Hilo. 2000 does extend east of 11.
Okay, I missed on Oahu.
As for HI 2000 on the Big Island the situation is a bit more ambiguous. Wikipedia both shows the highway as ending at HI 11 and further east at Railroad Avenue. Signage in the field seems to be very minimal, even along Puainako Street west of HI 11 there don't seem to be any HI 2000 shields. Heading north on HI 11 to the HI 2000 intersection it shows the highway as crossing HI 11. But from the north, it shows HI 2000 as just heading west from HI 11.

So the signage is confusing as to whether or not it really extends east of HI 11. Considering this is a temporary designation it may not matter much in the end.

Add Alpine County to the list, too. There are four three-way (4/207, 4/89 and 88/89 twice) but no four-way SH intersections.

A few more can be added to the list: Sierra, Plumas, and Lassen Counties. Sierra's not surprising; only two actual junctions in that county: the CA 49/89 pair at each end of their multiplex. NE CA is rife with multiplexes, largely due to the topology plus the presence of CA 89, which features no less than 7 multiplexes along its length (8 until the one with CA 4 was eliminated).
