CDOT to begin a bridge joint replacement project on I-70 in Glenwood Canyon

Travel Advisory

June 25, 2025 - Northwestern Colorado - Drivers to expect delays through work zones

Garfield/Eagle Counties — The Colorado Department of Transportation and contract partner, KSK LLC, is scheduled to begin a bridge joint replacement project on Interstate 70 in Glenwood Canyon starting mid-July. The project will replace 23 bridge joints and conduct guardrail repairs from mile points 116 to 133. This is a two-season project, with anticipated completion expected around Fall 2026, and a winter shutdown is planned when the weather becomes too inclement for crews.

Project Benefits

Bridge joints connect the roadway to elevated bridges, allowing for expansion and contraction as vehicles drive over them, which is critical infrastructure for safe roads for motorists. The 23 structures in Glenwood Canyon will be worked on at or near the following areas:

  • Exit 119 No Name
  • Exit 122 Grizzly Creek Rest Area
  • Exit 123 Shoshone Power Plant
  • Exit 125 Hanging Lake Trailhead
  • Exit 129 Bair Ranch Rest Area

Traffic Impacts

For this project, traffic control may involve a lane closure up to two and a half miles long in either the westbound or eastbound I-70 lanes through Glenwood Canyon. Motorists should expect one lane closure per direction while the bridge joints are replaced.

  • Vehicles will be reduced to one lane traffic in either direction, throughout the duration of the project
  • Daytime work hours are 7 a.m. to 7 p.m., Monday through Friday
  • The speed limit will be reduced to 35 mph through the work zone

In addition to this project, critical construction projects are underway across the I-70 Mountain Corridor. Visit the I-70 Mountain Corridor page for additional maps and resources for all I-70 projects taking place between Golden, CO and Utah border this summer.

The project will replace 23 bridge joints and conduct guardrail repairs on eastbound and westbound I-70 throughout Glenwood Canyon.
