State Highway 145 (SH 145) is a state highway in western Colorado. It runs for 116.879miles between U.S. Route 160 (US 160) in Cortez and SH 141 near Naturita.
The route begins in the south at its intersection with US 160 in the eastern portion of the city of Cortez. The route winds northward through the towns of Dolores, Rico, Sawpit, Placerville, Norwood, and Redvale before terminating at the junction with SH 141 about 4miles east of Naturita. Just north of its midpoint between Rico and Sawpit, the road also passes very near and provides access to the town of Telluride as well as Trout Lake.
On May 24, 2019, a large boulder fell onto a section of SH-145 near Dolores and covered the roadway. It was deemed too impractical to move or destroy, and the highway was instead realigned in July, and the rock, named Memorial Rock, was dubbed a landmark.[2] [3]
