100 years of US routes: 1926-2026
US route endpoint in
1927-1937
This photo was taken looking west on 18th Street, which is now Business US 34. 18th St ends at the intersection in the distance (8th Avenue); beyond that is the University of Northern Colorado campus:

Today 8th Av serves as the north-south business loop, but before today's US 85 bypass was built, it was mainline US 85. So -- starting in 1927, and for about four years -- that was the west end of US 38. Then, from about 1932 to 1937, US 6 ended there:
c. 1931, CDoT
c. 1932, CDoT
When US 6 was changed to run through Denver and on to California, this road became US 34. (But US 34 never ended there: when it was extended to Greeley, it continued west through Loveland and Estes Park and over Trail Ridge Road in Rocky Mountain National Park, ending in Granby CO.)
By the time the photo above was taken, the sign directing US 34 traffic to the right was incorrect. Business 34 does head north on 8th Av (and then west again on 10th Street). But mainline US 34 is routed onto a newer bypass, which is about a mile south (left) from there. But at least it was better than what was there by 2006: that entire assembly had been removed, with no replacement. Here are a couple photos from northbound 8th Av (old US 85):

The destinations on that sign hearken back to a time when mainline US 34 and US 85 traffic was routed through this intersection. The assembly in the background is shown close-up here:
