Travel Advisory

November 15, 2021 - Southwestern Colorado

OURAY & SAN JUAN COUNTIES — The Colorado Department of Transportation completed work on the US Highway 550 culvert repair project earlier this month. The project, located in Ouray County, was approximately 10 miles south of Ouray and just north of the Red Mountain Pass summit, from mileposts 80 to 81.5. The project consisted of removing and replacing culverts at two locations, as well as stabilizing stream banks. The project also extended and widened the existing parking and pullout area on the west side of the highway near the pass summit.

US 550 Culvert Project

This project benefits motorists by providing a safer highway when snow runoff or rainstorms occur. Improvements at two existing culvert sites allow water to flow unobstructed under the roadway. The improvements to the parking and pullout area provide more space for travelers and backcountry users who may need to stop, pullover, or park along the pass.
