US routes that are signed perpendicular to the direction implied by their number

[GaryV]

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.

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.

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.

Also US 130, US 202, US 206, US 211, US 222, and US 522.

US 211, especially.  The reason I picked US-430 over any of the others is this:

US-430 — commissioned in 1926
US-211 — commissioned in 1926
US-222 — commissioned in 1926, but originally ran only a diagonal
US-522 — commissioned in 1926, but originally ran only a rather east-west diagonal
US-130 — commissioned in 1927, but runs a diagonal
US-206 — commissioned in 1934
US-202 — commissioned in 1935
