Highway surface treatment set for US 160, Cortez to Mancos Hill —

The Colorado Department of Transportation and contractor United Companies from Grand Junction, CO will begin a project on Wednesday, May 29 following the Memorial Day holiday (not May 20 as previously announced). to provide maintenance surface treatments to US Highway 160 east of Cortez and to a short section of CO Highway 145. The project will enhance safety for the traveling public, providing a smoother surface for vehicles and a newly striped highway offering better visibility for drivers. These improvements are part of CDOT’s statewide initiate for Whole System. Whole Safety.   

Specifically, the work zone will stretch for approximately 22 miles on US 160 between mile point 40, near the junction with CO 145, and MP 61.85, at the top of Mancos Hill, the Montezuma/La Plata county line. This will include the ramps and bridge deck on the Mesa Verde interchange and the section through the town of Mancos. The work zone on CO 145 begins at MP 0, at the US 160 junction, and extends north to MP 1.34, to the end of the highway’s curb/gutter section.
