From Wolf Creek Pass, US 160 continues northeast and turns east at South Fork. At Monte Vista, an overlap begins with US 285, which continues southeast into Alamosa. It turns east, then goes northeast to go through North La Veta Pass, then continues east to Walsenburg, where it intersects Interstate 25 (I-25).
From Walsenburg, US 160 continues south with I-25 to Trinidad, then turns northeast to intersect US 350. It continues east, passing through the Comanche National Grassland before intersecting the concurrent US 287 and US 385 south of Springfield. It continues east and enters Kansas east of Walsh.
As commissioned in 1930 the western terminus was Trinidad.[1] In 1939, US 160 absorbed all of former route U.S. Highway 450 which ran from US 50 at Crescent Junction, Utah to US 85 at Walsenburg.[2]
In 1970, many US Highways in the Four Corners region were realigned. US 160 was diverted southwesterly from Cortez to follow its present route past the Four Corners into Arizona, absorbing the route numbered U.S. Highway 164.[3]
In 2021, the portion of the highway between Walsenburg and the highway's junction with Colorado State Highway 12 was designated a National Scenic Byway. The designation, which includes State Highway 12 and the county roads over Cordova Pass, is called the Scenic Highway of Legends.[4]
