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

US491 in Utah tends to be signed east-west, though most of the route is north-south.

US491 in Utah tends to be signed east-west

This was true in the past, but as of the last time I was down there (November 2017 - see photos below), the signage had all been changed to north-south. However, mile zero is still at the "west" end in Monticello instead of at the south end at the Colorado line.

That's not how the 3-di on the US system works. The odd and even thing doesn't apply the same way as the interstate system. The 3-di US highways go in numerical order along the parent highways route. So the first spur gets 1xx, then 2xx and so on.

pssssst  ...  the i in 3di stands for interstate.

True. Another thing is a lot of the 3 digit US highways are several hundred miles long where a 3-di isn't. Doesn't the 300 mile or at least two state limit get used on 3 digit US highways like the parent routes?

It still applies.

I thought so considering that US-223 enters Ohio just to end at the first exit along a multiplex with US-23. I've said before that it should be decommissioned and made a state highway. Or US-223 should go further into Ohio.

IMHO, US-23 should be rerouted to follow I-75 and OH-15 to Carey, with US-223 using an alignment of OH-51, I-280, OH-420, US-20, and (current) US-23 to Carey

In my own travels I have totally messed up at that wrong way multiplex 23 does with 75. However I did find the cleanest Waffle House around it's not even a year old it's st the 23/20 Exit.

Anyway back on topic, I agree with that or 223 can do another route and go to Newark or somewhere around there so it gives it some kind of identity. 223 is pointless as is as a US highway though.
