Wyoming 585

Routing

Wyoming 585 is a primary state route, connecting U.S. 85 at Four Corners (north of Newcastle) with Business Loop I-90 and U.S. 14 in Sundance.

History

Wyoming 585 first appeared in 1933 and has maintained its alignment since that time. At that time, U.S. 85 had four U.S. auxiliary routes: U.S. 185, U.S. 285, U.S. 385, and U.S. 485. Planners possibly hoped to make Wyoming 585 into a U.S. 585, but that never happened. DeLorme's 1992 Wyoming Atlas and Gazetteer mistakenly refer to Wyoming 585 as U.S. 585. It never was a U.S. route, not even when U.S. routes as short as 28 miles long were common (see U.S. 116, 320, 420, etc.).
