US 160 Wolf Creek Tunnel Drainage

About the Project:

The project will update the existing underdrain system that runs in the center of the eastbound travel lane with a larger, improved drainage system. Crews will install manholes at both ends of the tunnel to improve maintenance access. Additional work includes the replacement of several concrete panels and installation of delineators near the drainage structures.

The tunnel work zone is located on the east side of Wolf Creek Pass, approximately 10 miles west of South Fork and seven miles east of the Wolf Creek ski area (Mile Point 174).
