About I-70 Glenwood Canyon Surface Improvements

This eight-month improvement project includes resurfacing I-70 with a placement of thin bonded polyester concrete overlay, replacement of bridge joints and bearings, new pavement markings and ADA ramp improvements at rest areas. Construction will occur within approximately 6.2-miles on I-70 in the Glenwood Canyon, from Mile Point 117.6 to MP 125. The project is scheduled to be complete in October 2020.

Polyester concrete overlay is the primary construction activity for this project. Upgrading this section of roadway will minimize the need for annual repairs as this road surface application is more durable and has a significantly longer lifespan than asphalt. This project will provide an improved driving surface and help ensure the longevity and safety of our infrastructure.

Ongoing Intermittent Stops

During work hours, Mondays through Fridays, 7 a.m.-7 p.m., motorists should plan additional travel time through the canyon. Crews are completing final work activities including barrier installation and a bridge joint replacement. In order to move equipment through the work area, brief, intermittent stops will be required.

Intermittent stops and lane closures are expected to wrap up with project completion at the end of October.

Glenwood Canyon Bike Path and Rest Areas

(No Name, Grizzly Creek, Shoshone, Hanging Lake, Bair Ranch)

All rest areas, river put-ins and the bike path in Glenwood Canyon remain closed following damage from the Grizzly Creek Fire. These closures allow CDOT, law enforcement and emergency services to quickly evacuate I-70 and Glenwood Canyon, and to protect travelers and recreationists from possible mudslides, debris flow, rockfall and other hazards.

Travelers are urged to “know before you go.” Gather information about weather forecasts and anticipated travel impacts and current road conditions prior to hitting the road by visiting
