In 1951 the US 377 designation was extended to Del Rio TX. This first shot was taken heading south on Veterans Boulevard (renamed from "Avenue F"); it was 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 was where US 377 ended; the photo below shows signage at the intersection:

Eastbound US 90 and southbound US 277 were directed left at the intersection (Gibbs Street), but 377 ended 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 (also in about 1951), 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. The photo below was looking east on Garfield:

This assembly was a little strange, too: to the left is Spur 297. And there was no mention here of US 377, US 277, or Spur 277. Anyway, it's possible that US 377 once began to the left here. We'll head that direction and return to the former terminus of US 377; this next photo was taken across the viaduct, at the other end of Spur 297:

Karners, Dec. 2014

There was no assembly here in 2013. Several of the signposts at this intersection were replaced in 2014, and they were not entirely accurate. The one shown above made it look like 90, 277, and 377 all went both straight and right, but US 377 actually began straight ahead. In the background was the first northbound confirming marker for 377, shown in more detail below:

Karners, Dec. 2014

That was also fairly new; prior to that the first northbound US 377 sign was another block ahead:

The photo below was taken from eastbound Gibbs (TX Spur 239):

Lots of information to convey here, so multiple sign trees were used. The actual intersection with Veterans was signed thus:

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

me, Aug. 2013; click here to view full-res version

This was westbound US 90 and northbound US 277, each of which continued to the right. Also to the right was the south beginning of US 377.

Loop 79 around Del Rio was built in 2008. Below is a 2013 view of it, as seen from eastbound US 90:

Google Maps Street View, Mar. 2013

That's on the east edge of town; the entrance to Laughlin AFB is just ahead. Around the beginning of 2016, Google Maps began indicating that all US highway designations had been routed around the city via this former state highway loop. So straight ahead is still eastbound US 90, but now to the right is southbound US 277, and to the left is westbound US 90, northbound US 277, and the south beginning of US 377.

In 1991 OK DoT extended the US 377 designation further north, to its present terminus at Stroud... however, signage there made 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):

McMahon, Dec. 2002

(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:

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?
