Travel Advisory

Sept. 14, 2026 - Denver/Central Colorado - Expect significant delays up to 30 minutes or longer; alternative route advised

Jefferson County - To safely complete bridge repairs, the Colorado Department of Transportation and its contractor, Myers and Sons Construction, will implement two extended weekend closures of Interstate 70 during the weekends of Sept. 18 and Sept. 25. Each closure will last up to 83 hours while crews complete critical bridge repairs on the eastbound and westbound I-70 bridges over Kipling Street (Colorado Highway 391). Completing the work during full closures allows crews to work more efficiently, shortens the overall construction schedule and reduces repeated traffic impacts for motorists.

The first extended weekend closure of westbound I-70 will begin at 7 p.m. Friday, Sept. 18, and end at 6 a.m. Tuesday, Sept. 22. The second extended weekend closure of eastbound I-70 will begin at 7 p.m. Friday, Sept. 25, and end at 6 a.m. Tuesday, Sept. 29.

During the closures, I-70 traffic will be routed through the Kipling Street Interchange using the on- and off-ramps before returning to the interstate. Because the on- and off-ramps will serve as temporary I-70 travel lanes, motorists will not be able to enter or exit I-70 at Kipling Street. Kipling Street also will be closed in both directions at the interchange. Motorists should follow the posted detour via West 44th Avenue, Ward Road, West 58th Avenue/Ralston Road, and Wadsworth Boulevard.

During the westbound closure, the Wadsworth Boulevard northbound and southbound on-ramps to westbound I-70 will be closed. A detour will be in place via West 44th Avenue to Ward Road. During the eastbound closure, the Ward Road on-ramp to eastbound I-70 will be closed. A detour will be in place via West 44th Avenue to Wadsworth Boulevard. Bicyclists and pedestrians will be detoured using Garrison Street.
