US 320 was a short connector route between US 20 at Shoshoni and US 87W at Riverton (which was a precursor to today's US 287). While the entirety of its former route is now part of US 26, that didn't happen until 1948. So as far as I can tell, US 320 was decommissioned simply because it was too short to be considered a legitimate US route. Below are photos of modern signage at the historic junctions. This first one is in Riverton, looking north on WY hwy. 789, or Federal Boulevard:

When the US routes were first commissioned, the road northwest out of Lander (today's US 287 through Ft. Washakie) wasn't used as a highway. Instead, northbound US 87W traffic had to go northeast from Lander to Riverton, then continue northwest via modern US 26. In other words, the photo above shows signage from the perspective of someone on northbound US 87W, which would've continued to the left on Main Street via today's US 26. Straight ahead was the west beginning of US 320; below is a close-up of the signage:

The photo below is looking the opposite direction (south on Federal):

Elbert, July 2005

That would've been the west end of US 320; ahead was southbound US 87W, and northbound was to the right. Below we're looking east on Main/US 26:

Teresco, Jul. 2003

That was southbound US 87W, which continued to the right. To the left was the west beginning of US 320. After heading a mere 22 miles, a driver heading that direction would come to the junction pictured below:

Teresco, Jul. 2003

That's looking east on 2nd Street in Shoshoni; that intersection with Idaho Street marks the historic east end of US 320. Below we're looking the opposite direction (west on 2nd/US 20):

Elbert, July 2005

US 20 continues to the right on Idaho; straight ahead was the east beginning of US 320. The photo below shows the view from southbound Idaho:

Elbert, July 2005

That's eastbound US 20, which continues to the left on Main. Until 1938, to the right was westbound US 320.
