In 1951 the US 377 designation was extended to its current terminus in Del Rio TX. This first shot was taken heading south on Veterans Boulevard (renamed from "Avenue F"); it's the last southbound US 377 sign:

As you can see, the designation is co-signed with US 90 and US 277. The yellow traffic signal in the distance is where US 377 ends; the photo below shows signage at the intersection:

Eastbound US 90 and southbound US 277 are directed left at the intersection (Gibbs Street), but 377 ends here. Straight ahead is a viaduct over some railyards; today that's designated TX Spur 297. But when US 277 was first extended south of Del Rio (in about 1945), it didn't turn left here with US 90. Instead, it continued ahead over the viaduct to Garfield Street. Here's how that intersection is signed today:

There mainline US 277 turned left (east towards Eagle Pass), whereas Spur US 277 turned right (southwest) to the Mexico border crossing. Garfield is still Spur US 277, as far as I know, despite the signage here (the real TX Spur 277 is in Coupland, way over near Austin). The reason I bring all this up is: since the US 277 designation made it to this point until about 1985, it's possible that US 377 was signed to this junction as well. Below we're looking east on Garfield:

This assembly is a little strange, too: to the left is Spur 297. And there is no mention here of US 377, US 277, or Spur 277. Anyway, it's possible that US 377 once began to the left here. But now we'll return to the current terminus of US 377; the photo below was taken from eastbound Gibbs (TX Spur 239):

Lots of information to convey here, so they've used multiple sign trees. The actual intersection with Veterans is signed thus:

The south beginning of US 377 is to the left. This next shot is from the opposite direction (west on Gibbs):

This is westbound US 90 and northbound US 277, each of which continue to the right. Also to the right is the south beginning of US 377. When you make that turn onto Veterans, the first northbound US 377 sign is shown below:

In 1991 OK DoT extended the US 377 designation further north, to its present terminus at Stroud... however, signage there makes it difficult to know exactly where. The photo below is looking north on US 377/OK hwy. 99 (8th Avenue) at historic US 66/modern OK 66 (3rd Street):

(Yes, you'll note that sign goofs abound at this intersection). Here, you'd get the impression that the US 377 designation continues ahead about a half-mile to the I-44 interchange. Same thing heading east on 3rd...

McMahon, Dec. 2002

...and that is correct, based on OK DoT route logs: US 377 does end at I-44. Funny thing is, though, Martin reported that north of here there was absolutely no mention of US 377. Even the signage on I-44 mentioned only OK 99...

Stuve, Mar. 2003

...although by 2010 US 377 had been signed from I-44:

Below is the first southbound sign:

You can view the full versions of these photos - and read Martin's report - on his page. This approx. 120-mile extension of US 377 north of Madill to Stroud was apparently done without AASHTO's approval. That makes it perhaps the single most blatant example of an AASHTO policy violation. And it's not a good precedent: the uniformity and integrity of the US route system depends on the voluntary cooperation of the state highway departments. But don't be too quick to place all the blame on OK DoT. From what I've been able to tell, they had been trying to get a US route designation approved for the Madill-Ada corridor for literally decades. Starting in 1952, OK DoT had at least a dozen different proposals rejected by AASHTO. They tried all kinds of approaches, attempting to extend US 177, US 377, and even US 169, such that they would pass through Ada. So what is it about this corridor that AASHTO keeps rejecting it as a US route?
