100 years of US routes: 1926-2026
Endpoints of
US 420 was a short connector route between US 20 at Cody and US 310 at Deaver:
c. 1933, WY DoT
Deaver
Most of it was soon swallowed up by an extension of US 14 (now Alt. US 14), but the 11-mile segment between Deaver and Garland was redesignated as Wyoming state highway 114. This photo shows signage that was formerly posted at that junction:

That was northwestbound on US 310, which continued to the right. To the left was historically the beginning of US 420. So the junction where WY 114 ends at US 310/WY 789 is the modern functional equivalent of the historic end of US 420...

...however, US 420 did not skirt the west side of Deaver (as WY 114 does today). Instead, traffic came into town on 1st Street, then turned north on Central Avenue, crossed the railroad, and ended at US 310. In the preceding photo, that junction is about a tenth-mile to the right. This image was taken looking north on Central; US 420 essentially ended where the stop sign is now (except at the time this intersection was configured as a "Y" junction). This location happens to be right across the highway from what is now the Wyoming 310 Cafe:

The west end of US 420 was at its junction with its parent route (US 20) in Cody. In 1933, most of US 420 was retired by a westward extension of US 116... and then the next year, US 116 itself was eliminated by a westward extension of US 14.
