Culvert Improvement project to begin on August 2, US 550 Red Mountain Pass

News Release

July 23, 2021 - Southwestern Colorado

OURAY & SAN JUAN COUNTIES — The Colorado Department of Transportation will begin work on the US 550 culvert repair project on August 2. The project is located in Ouray County, approximately 10 miles south of Ouray and just north of the Red Mountain Pass summit, from mileposts 80 to 81.5. 

This project will benefit motorists by providing a safer highway when snow runoff and rainstorms occur. Improvements at two existing culvert sites will allow water to flow unobstructed under the roadway. This project will also improve existing parking/pullout areas for travelers along the pass. 

The project will consist of removing and replacing culverts at various locations, as well as stabilizing steam banks and extending the existing parking/pullout area on the west side of the highway. Williams Construction Contractors of Norwood, Colorado has been selected for this project. Work is expected to begin the first week of August and be completed later this year, weather permitting.

Travel Impacts 

Travelers will encounter brief lane closures, lane shifts and shoulder closures beginning August 2 and continuing through the fall. Motorists are urged to use caution and watch for heavy equipment. Any temporary closures are to ensure the safety of the workers and the traveling public. Motorists should slow down, drive with caution and give themselves extra travel time.
