A major bridge maintenance project along Interstate 70 in Glenwood Canyon is set to begin in mid-July, according to a news release from the Colorado Department of Transportation.

Contractor KSK LLC of Grand Junction will lead the effort, which includes replacing 23 bridge joints and repairing damaged guardrails between mile points 116 and 133. The work is scheduled to span two construction seasons, with a pause during the winter months and final completion anticipated in fall 2026.

This project will benefit motorists as bridge joints connect roadway to elevated bridges and require expansion and contraction as vehicles drive over them, making it critical infrastructure for safe roads. 

Work will take place near the following areas in Glenwood Canyon:

• 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

Drivers should expect lane closures up to 2.5 miles long in either direction throughout the duration of the project. I-70 will be reduced to one lane in each direction at times, with crews working from 7 a.m. to 7 p.m. Monday through Friday. The speed limit through the work zone will be reduced to 35 mph.

In addition to this Glenwood Canyon project, CDOT is continuing several major construction efforts across the I-70 Mountain Corridor, which stretches from Golden to the Utah border.
