U.S. Route 85 (US 85) is a part of the U.S. Highway System that travels from the Mexican border in El Paso, Texas, north to the Canadian border in Fortuna, North Dakota. In the state of Wyoming, US 85 begins at the Colorado state line south of Cheyenne and ends at the South Dakota state line northeast of Four Corners.[1][2]

Route description

US 85 enters Wyoming from Colorado eight miles (13 km) south of Cheyenne. Just south of the city it joins with US 87 Business, and 1.2 miles (1.9 km) further north it intersects I-80 where it runs concurrently with I-180, the only fully at-grade Interstate Highway in the U.S.[3] The I-180 concurrency ends at I-80 Business and US 30 in downtown Cheyenne before continuing 2.9 miles (4.7 km) to I-25 at exit 12. It joins with I-25 and US 87 in a 4.8-mile (7.7 km) concurrency until US 85 leaves at exit 17 and travels 45 miles (72 km) northeast towards Meriden. From there it heads 39 miles (63 km) north to Torrington, where it meets with US 26 and runs concurrently for 10 miles (16 km) until Lingle. US 85 travels 46 miles (74 km) to Lusk where it meets US 20 and US 18. It shares the next 47 miles (76 km) with US 18 to Mule Creek Junction, and 33 miles (53 km) later meets US 16 near Newcastle. From here it is 29 miles (47 km) until it enters South Dakota in the Black Hills.[1][2]
