U.S. Highway 160 will be fully closed nightly for one week, from 9 p.m. to 6 a.m. Monday, Sept. 20 to Friday, Sept. 24 east of the Highway 151 junction, near Chimney Rock National Monument and Lake Capote at mile marker 127.

The intersection of Highway 160 and Highway 151 will remain open, but drivers will be able to travel only westbound (toward Bayfield and Durango) during nighttime closure times. Eastbound travel (toward Pagosa Springs) will not be allowed, as the closure area is just east of the intersection.

During the nighttime closures, drivers seeking eastbound/westbound access on Highway 160 are advised to arrive at the closure point before 9 p.m.

Otherwise, travelers may consider an alternate southern route via U.S. highways 84, 64 and 550, through New Mexico. A detour at the work zone is not available and vehicles are not permitted to stop or wait overnight.

Daytime work will not take place during the closure. Daytime construction activity will resume Sept. 27. A temporary signal will be in place 24/7, reducing vehicles to a single-lane and alternating traffic intermittently in either direction. Drivers can expect short delays. Speeds are reduced to 30 mph in the work zone.
