Seems like 90% of the highway has exit numbers posted between 20 (TXLp375) & 32 (Sean Haggerty Drive, which will need a point added).
LOL I was purposefully dragging my feet on converting this on the long-shot hope that TXDOT might convert the numbers to something more sensible.
FWIW, US54 doesn't use ULRS; the exit numbers increase south->north, just starting at 20 for whatever reason.
Also in El Paso,
TXLp375 and
TXSpr601 also start at 11 & 20 respectively, which also appear unrelated to ULRS.
I guess if these have exit numbers then US54 should too.
I-110_S may no longer exist. The former westbound exit is now part of the I-10 interchange. Eastbound traffic from I-110 merges in at the Rosa Avenue underpass, so logically there may still be a short I-110 north/US 54 east overlap. I suppose we could fudge a bit and use 21A for I-110_S and 21B for I-10.
TLDR, I think this is a reasonable fudge. Done.
24A RaiDr (but it's for Fred Wilson Avenue from both directions, with a point at the same place as 24B, so merge them as 24?)
Merged.
32 could be added at Sean Haggerty Drive, but it's not an interchange
Added. The wide median and ghost mainlanes signal TXDOT's intent to eventually upgrade to full freeway. I've seen at-grade numbered exits before -- Nova Scotia comes to mind, where there's also
a similar numbered non-exit from a to-be-constructed mainline. This is the first one I've seen in TX though.
Everything else in neroute2's post also implemented.
