Wyoming Highway 585 (WYO 585) is a 28.000-mile (45.062 km) north-south state highway in Weston and Crook counties in northeastern Wyoming, United States, that connects U.S. Route 85 (US 85) in Four Corners with Intersate 90 Business / U.S. Route 14 (I-90 BL / US 14) in Sundance.
Route description
[edit]Weston County
[edit]WYO 585 begins at a T intersection with US 85 (CanAm Highway) in the unincorporated community of Four Corners on the Canyon Springs Prairie[2] in the northeast corner of Weston County. (US 85 heads north towards the Wyoming-South Dakota state line and then on towards Lead in South Dakota. US 85 heads south towards Newcastle and Mule Creek Junction.) From its southern terminus, WYO 585 proceeds north-northwesterly as a two lane road (until it enters Sundance) for just over 9.6 miles (15.4 km) to pass through what little remains of the unincorporated community of Horton before crossing the Weston-Crook county line and entering Crook County.[3]
Crook County
[edit]Shortly after entering Crook County, WYO 585 crosses the Inyan Kara Creek[4] and then Soldier Creek[5] as it continues proceeding north-northwesterly. WYO 585 connects with the east end of County Road 49 (CR 49 / Steve Banks Road), roughly ten miles (16 km) north of the county line. (CR 49 heads due west to end at Wyoming Highway 116. From the same intersection Ferderer Road, a private road, heads briefly east.)

About 8.3 miles (13.4 km) farther, and after crossing Silver Creek and entering the city of Sundance, WYO 585 reaches Interstate 90 (I-90), exit 187, at a diamond interchange. (I-90 heads east to run concurrently with US 14 and on towards Beulah and then Spearfish and Rapid City in South Dakota. I-90 heads west towards Moorcroft and Gillette.) Approximately one-half mile (0.80 km) northwest of I-90, WYO 585 reaches its northern terminus at a intersection with I-90 BL / US 14 (East Cleveland Street), after crossing Sundance Creek. (I-90 BL. / US 14 heads east towards Beulah, Spearfish, and Rapid City. Dakota. I-90 heads west towards Devils Tower Junction [also known as Carlile Junction],[6] Devils Tower, and Hulett. North 6th Street continues north from the intersection for several blcoks before ending on the north side of town.)[3]
History
[edit]WYO 585 was commissioned in 1933 and has kept its original alignment since then. In 1933, US 85 had four US auxiliary routes: US 185, US 285, US 385, and US 485. It was possible that planners wanted WYO 585 to be made into US 585; however, that never happened.
