History
Wyoming Highway 320 was originally designated in Fremont County along what is now Wyoming Highway 789 between Lander and Shoshoni between 1939 and 1950. It was originally US 320 between 1926 and 1938 but in 1939 was recommissioned as Wyoming Highway 320. In 1940, when US 287 and Wyoming Highway 287 were rerouted, Wyoming 320 was extended southwest to Lander. WYO 320 maintained this until 1950, when US 26 was commissioned. WYO 320 lasted until 1954, when Wyoming Highway 789 was commissioned, thereby replacing it.
Additionally, The highway that currently carries Wyoming Highway 320 was originally part of US 87 and before that US 185 (US 185 between Cheyenne and Casper was decommissioned and replaced with US 87 in 1936){{cite web|url=http://www.aaroads.com/west/us-185_wy.html|title=U.S. Highway 185 (Decommissioned)|publisher=AARoads}}{{self-published inline|date=January 2017}} Between 1956 and the 1980s, as more of Interstate 25 was completed, the original routing of US 87 was recommissioned on the Interstate 25 freeway.{{cite web|url=http://www.aaroads.com/west/us-087_wy.html|title=U.S. Highway 87|publisher=AARoads}}{{self-published inline|date=January 2017}}
