State with most intrastate US Highway Designations

[roadman65]

Many states such as NJ and FL have US Highways that are within their state only and the latter has road too that are even shorter than most of their state highways as well.

NJ has both US 46 and 130 with US 206 being iffy as part of that road (though less than a mile) is in PA making it a two state road designation.  Florida has both US 92 and its child US 192.

Colorado has its own US 350 as well, but Texas has many such as US 57 and 69 with US 175 and some others.  I have not been able to come up with the correct count, but I will say at this time that Texas wins in this category as I am guessing that other states that have one state US routes mostly have at least one or two.

Any other states that have more than Texas or is the Lone Star State king in one state US routes?

[US 89]

US 117, 158, and 264 are all located entirely within North Carolina. Of those, only US 158 is longer than AASHTO's 300-mile recommendation.

[TheHighwayMan3561]

US 69 isn't intrastate, did you mean 96 I assume?

[Beltway]

Virginia has US-58, Alt. US-58, US-211 and US-360.

[Max Rockatansky]

Florida used to have a couple more intrastate US Routes.  US 94 and US 541 immediately come to mind.  US 441 and US 98 used to be exclusively Florida US Routes.

Virginia has US-58, Alt. US-58, US-211 and US-360.

A tiny bit of US 58 (less than a mile) is in Tennessee.

[hotdogPi]

I have a list of all of them. Texas wins with 57, 96, 175, 181, and 290.

US 117, 158, and 264 are all located entirely within North Carolina. Of those, only US 158 is longer than AASHTO's 300-mile recommendation.

In fact if AASHTO enforced the "All intrastate US routes less than 483 km long should be eliminated" guideline US 158 would become the only intrastate US route.

[hbelkins]

Virginia has US-58, Alt. US-58, US-211 and US-360.

Necessitated by the construction of the Cumberland Gap Tunnel, which removed US 25E from Virginia.

Incidentally, extension of US 311 into Virginia eliminated it as a qualifier in North Carolina.

That's correct, and note that TX is also the only state with two 2-digit intra-state US routes, which could be considered particularly egregious.  On the other hand, TX is a very big state.

NC gets the silver with three intra-states, but as mentioned it had four for almost 80 years, until US 311 was extended in 2012.  Three states have two, and six states have one.

Now, for people who have a philosophical problem with intra-state US routes, do you also have a problem with what I call "stealth violators"?  These are US routes that escape scrutiny because they do exist in more than one state, but not by much.  The prime example, US 206, has been mentioned: its length in PA is less than a half-mile.

If you have a problem with that type of thing, then you might regard South Carolina with the stink eye, because it is the king of stealth violators.  There are five US routes that exist only in SC, except for segments of 25 miles or less that poke into adjoining states.

Even after the correction on US-58, Virginia has three -- Alt. US-58, US-211 and US-360.

On the sideline is US 199.  It is the last remaining route that branched off as an US x99 which is still a US route.

US 730.  At least US 30 is still around to blame...LOL!  For such a BIG number it is a very small route of around 42 miles running in NE Oregon and SE Washington with a beautiful view of the Columbia River. 

Oregon's last remaining intrastate US route is 197, which connects Madras to The Dalles.  It is an easy and scenic clinch!  We used to have US 126, which has an interesting history. Part used to be US 28, which no longer is an active number, part had to wait to be built so Eugene and Florence would have a direct connection )1957) and then came the changing of the guard.

197 enters WA.

197 enters WA.

It does not look like it does in the atlas.  Are you saying US 197 terminates at SR 14 in WA?

Yes.

Isn't that strange?  One would think a "natural" terminus would be US 30 on the south side of the Columbia River instead of the north side on a state route.  Thanks for letting me know!

Yes that is US-197's northern terminus.

I'm guessing that the reason US-197 extends into Washington is so that it can get it's second state since it's well under 300 miles long. Notice though how Washington ends it at the first possible chance it gets.

[Rothman]

I doubt that.  Probably just an old spur off of US-97 that was truncated or re-routed over time.

[Flint1979]

Not on topic or anything but I noticed as well how at US-197's northern terminus I-82 is mentioned, I-82 is almost 100 miles away the sign says JCT I-82 you'd think it'd be in somewhat close proximity of this interchange. https://www.google.com/maps/@45.6481847,-121.155937,3a,15.3y,26.28h,92.97t/data=!3m6!1e1!3m4!1sslzzL--Nq2073uaBIFL2-w!2e0!7i13312!8i6656

So I'm going to be driving for almost 100 miles wondering when the hell I'm going to reach I-82 lol.

[Flint1979]

After doing a little research on it, US-197 use to turn east to end at US-97 in Maryhill. It was scaled back to it's current terminus in 1979 but AASHTO still considered it part of US-197 until 2006. So it was a longer route in Washington at one time.

It has that big of a number because it's on the west coast. The first digit of the spurs increased from north to south and east to west along the parent. So US-730 being on the west coast received a higher number.

[usends]

Even after the correction on US-58, Virginia has three -- Alt. US-58, US-211 and US-360.

If you're going to include bannered routes, wouldn't you also count Alt. US 15 and Alt. US 301?  But that's a huge can o'worms, and personally I don't think of bannered routes as standalone US routes.

There are also alternates for 11 and 460 in Roanoke, as well as what's signed as US 220A.

Not to mention an iteration of Alternate US 41 between Madisonville and Henderson, Ky. Or signed US 74A, US 321A and US 220A in North Carolina. Or the directionally-suffixed 45E and W in Tennessee, 49E and W in Mississippi, or 70N and S in Tennessee.

Originally, when WA 14 was US 830, both routes multiplexed east to end at US 97 in Maryhill; it's likely that section of US 197 existed because for a long time US 97 crossed the Columbia River on a ferry rather than a bridge (which was constructed in the early '60's); those who either feared or didn't want to wait for the ferry could detour via US 197.  Of course, when WA did its renumbering and US 830 was eliminated, US 197 remained on WA 14 for a while until WDOT deemed it superfluous (folks wanting to access The Dalles from US 97 could more easily do so on I-84 across the river).  I first passed through the us 197/WA 14 intersection back in 1987 -- and indeed 197 had an "END" shield assembly at that location.
