CO 91 Culvert Rehabilitation

About the Project:

The Colorado Department of Transportation and American West Construction, LLC will begin work on Monday, June 20 on Colorado Highway 91 to rehabilitate culverts. The culvert at Mile Point 10.52 will be cleaned out and lined and a headwall will also be installed at the outlet structure. The existing pipe at Mile Point 10.70 will be plugged and a new pipe will be installed under CO 91.

The project is located north of Leadville and near the Climax mine. Culvert improvements and replacement are necessary to protect roadways from heavy rainfall and maintain safe driving conditions if there is flooding. During normal business hours, lane and shoulder closures will be in place with alternating traffic.

Delays are anticipated to be no more than 15 minutes.
