US routes that don't fit the numbering/direction convention

[hbelkins]

Has anyone ever tried to compile a list of even-numbered US routes that are signed north-south, or odd-numbered routes that are signed east-west?

Here's my attempt:

US 1 -- signed E-W in Connecticut
US 4 -- signed N-S in New York
US 24 -- signed N-S in Michigan
US 33 -- signed E-W in Ohio, West Virginia, and Virginia
US 35 -- signed E-W in Ohio
US 42 -- signed N-S in Ohio
US 52 -- signed N-S in several states
US 62 -- signed N-S in New York
US 68 -- signed N-S in Ohio
US 220 -- signed N-S for its entire length
US 250 -- signed N-S in West Virginia
US 258 -- signed N-S for its entire length
US 522 -- signed N-S for its entire length

What have I overlooked?

US 202 varies by state

[SkyPesos]

For historical examples, anyone know if US 66 was signed north-south in Illinois? And US 6 in California?

[freebrickproductions]

Ain't US 98 signed North/South in part of Florida?

US 1 -- signed E-W in Connecticut

99% of all East-West signage has been changed to North-South.  A couple of stray remnants still exist in the wild.

US 62 is also signed North-South in PA

US 9 is E-W in DE
US 41 is E-W in south FL
US 175
US 178 is N-S in NC
US 218
US 550

US 83 goes E-W when it parallels the Rio Grande in TX.
US 96 goes N-S, and US 57 goes E-W.
I also think US 340 is signed N-S along most of its route.

Correct.  US-340 is posted as East/West for the 17-mile stretch in Maryland; the short east/west stretch in Loudoun County, Virginia is posted as North/South consistent with the remainder of the route up-and-down the Shenandoah Valley.

[LilianaUwU]

US 57 goes E-W.

But AFAIK signage is N-S to match the Mexican highway of the same number.

For historical examples, anyone know if US 66 was signed north-south in Illinois? And US 6 in California?

US 66 in Illinois was signed "ST. LOUIS" in the Chicago to St. Louis direction and "CHICAGO" in the St. Louis to Chicago direction.

If I understand correctly, that topic was discussed in this thread.

There was a brief time in the mid-1980s that US 175 was re-badged as N-S but I would guess that it was unpopular due to locals already knowing the route as E-W.  I never saw any news reports about it being done/undone.

(Seagoville, TX uses N-S for addressing on US 175.)

US 122 was signed N-S
US 240 was signed N-S
US 299 was signed E-W
US 666 was signed N-S

Several more likely would've been signed opposite if they had direction banners:  original US 117, US 170, US 260, original US 411 are examples.

US-101 changes from N-S to E-W in Washington before changing again to S-N.

Similarly, US-321 changes from N-S to S-N in Tennessee.

[hbelkins]

I've been on US 218, US 340, and US 550 and had meant to list them, but forgot.

Also, US 206 is signed N-S during its short run in Pennsylvania. I don't remember how the signage is over in New Jersey.

Correct.  Or else, just, you know, forget the banners entirely!

Also N-S.

i will never understand the routing of 321 north of Boone. It should just be truncated to US 421 in downtown Boone. The bit from 421 to 19E in Hampton can be state(s) route, as well as the "wrong way" bit south of Elizabethton.

Does anyone remember how US-102 was signed. (Not from personal experience.)

That early in the system's existence, the directions may not have been signed at all.

Do the 3-digit routes really count? They're numbered that because they intersect a 2-digit parent. In most cases, I think the default assumption is that if you have a child route, it's going to run perpendicular to its parent. US 220 being north/south would be the expected behavior rather than an abnormality.

Actually the vast majority of 3dus run parallel to their parent (not perpendicular), as illustrated at the bottom of this page.  US 220 is one of the few exceptions.

[Kulerage]

Still don't think 3dus highways should count. They're meant to be branches off the main highway to serve whatever purpose they must, and if it needs to run perpendicular to its parent, then so be it.

I've been wondering that this whole time.  I never assumed that 3-digit US routes were supposed to follow the usual odd/even convention.

Actually the vast majority of 3dus run parallel to their parent (not perpendicular), as illustrated at the bottom of this page.

And yet, from your same page:

"Unlike 2-digit US routes, there was never a guideline stating that 3-digit routes should run in a particular direction -- that is, no stipulation that north/south branch routes should be assigned odd numbers (so as to be considered branches of north/south main routes), and that even numbers should be given to east/west branch routes."

And I'd say US-430 is proof.

US 310 varies in Montana—in Rockvale it is signed east-west matching its overlap with US 212 (eastbound towards Laurel but westbound towards the Wyoming border), but in other places it is signed north-south. In Wyoming, it is consistently signed east-west with the opposite directions that are signed in Rockvale, so eastbound travels towards Greybull and westbound travels towards the Montana border.
