The route begins at US 550 in Silverton and runs for 740 feet (230 m)[2] to its terminus at a CDOT maintenance yard.

The route was established in the 1920s, when it began at US 550 in Silverton and headed north to Howardsville.

Except for the 740 feet (230 m) left today, the entire route was deleted north of Silverton in 2003; signage was removed along the entire route.

[3][4] The entire route is in Silverton, San Juan County.
