***SOUTHWEST TRAVEL ALERT***
Two highway closures in place for Southwest Colorado
CO 145 closed indefinitely due to rockfall and US 550 closed on Saturday 8:30 a.m. to 1:30 p.m. for a bike event
SOUTHWEST COLORADO – The Colorado Department of Transportation advises travelers that they will encounter two highway closures in southwest Colorado this weekend.
CO 145 ROCK FALL BETWEEN CORTEZ AND TELLURIDE
CO Highway 145 is closed indefinitely due to a significant rock fall which occurred late Friday afternoon. The slide is located approximately 12 miles north of Dolores, MP 22. The slide consisting of dirt, rock and two huge boulders which have destroyed the full width of the highway pavement, leaving a trench approximately eight feet deep across both lanes. The road is impassable at this time.
A geotechnical team, equipment, and supplies are being mobilized to the site, but it is not known when the road can be reopened. A boulder, the size of a building, which remains embedded on the highway needs to be blasted into smaller pieces in order to move it off the roadway.
