More US Routes than Ohio

US 98 is a toss up in Florida. Although the route is signed East/West througout the state, 98 goes northwest to southeast between Perry and West Palm Beach.

South Carolina following the US/Interstate numbering system, so US 52 is signed East-West, but North-South in North Carolina. Similar with US 178, and 276.

South Carolina is very unyielding with their cardinal directions.  Even on their state primary routes, odds are N-S and evens are E-W, so you end up with a lot of weird situations.  SC 14 is a prime example, runs mostly N-S but signed E-W.  If you're traveling north on I-385, SC 14 is multiplexed with it for a few miles.  At the southern end of the multiplex SC 14 breaks away on the left and is signed east (but actually goes south), and at the northern end it breaks away on the right and is signed west (but actually goes north).  I guess they feel that since they have so many diagonal interstates, they can just stick to the rules even when they make no sense.

I fully agree. Some things I can mostly understand, like US-176 or US-178 being signed as west-east, but SC-14 is inexcusable. The section from I-26 to Landrum is signed as "east," despite the fact that you're facing almost due west. SC-18 and SC-114 are possibly even worse, though: their "east" ends are actually slightly further west longitudinally than their "west" ends.

The silliest example is SC 20.

The change to strict adherence to even-odd directions is very recent and incongruent with the numbering system as it was laid out.
