Historic US highway endpoints in Dallas, TX

Originally US 75 came into Dallas on Ross Avenue, then turned south on Lamar Street. US 77 came in via Maple Avenue, jogged a few times, and ended up on Lamar. It met US 75 at Ross, so it could've ended at that intersection. The photo below is looking west on Ross:

That was southbound US 75, which continued to the left on Lamar. US 77 came in from the right on Lamar. It could've ended there, but to me it seems more likely that it would've been co-signed with US 75 to the left to end at US 80 (Commerce Street).

Meanwhile, US 67 came in on Gaston Avenue, which becomes Pacific Avenue downtown. That junctioned with US 75 at Lamar (about a block south of the intersection shown above), so US 67 could've ended there. The photo below is looking east on Pacific at Lamar:

US 75 ran across the photo (northbound to the left, south to the right). Straight ahead could've been the south beginning of US 67, but again, it seems more likely that it would've been co-signed to the right with US 75 to end at Commerce.

A few years later, US 175 was commissioned. It has always come into Dallas from the southeast on what is now known as the Hawn Freeway - but that corridor used to be known as "Seagoville Road", according to my 1947 map. Where northwestbound Hawn (and modern US 175) today veers due west to connect with the S.M. Wright Freeway (formerly S. Central Expressway), the 175 designation used to continue northwest on 2nd Avenue, past the State Fairgrounds and the Cotton Bowl. The 1936 TXDoT map seems to show it ending on 2nd at Commerce (US 80). However, it seems like US 175 should've been co-signed with US 80 along Commerce to Lamar, so that it could junction with its parent route (US 75). As a matter of fact, the photo below shows that US 175 was even signed from the old courthouse:

Bill Grunnah sent that; he writes:

"This photo is from the book "Dallas Then and Now" and dated from the 1930s. The book incorrectly identifies this as the east side of the Old Red Courthouse - actually it's the south side. The photo is taken from the corner of Houston Street and Commerce, looking north on Houston towards Main. Lamar is 4 blocks east of here."

It's hard to say whether US 175 actually began there, or if those were simply meant to be "TO" signs. Below is a photo from westbound Commerce at Lamar:

This was US 80, and the crossroad (Lamar) carried US 75. To me the most likely arrangement was that US 67 and US 77 began to the right with US 75, and that US 175 ended here. The photo below is from the opposite direction:

My guess is US 67/77 began to the left, while US 175 began straight ahead. It would've been co-signed with US 80 for nearly two miles, to the intersection shown below:

That's looking east on Commerce; the angle to the right is southeast on 2nd (perhaps the historic west beginning of US 175). US 175 still ends in Dallas, but no longer makes it into the downtown area - you can view its current endpoint on my main US 175 page. US 67 and US 77 didn't end in Dallas for long - for decades they've each served Mexico border crossings.
