Travel Advisory

June 10, 2026 - Northeastern Colorado - Detour routes scheduled Friday night through Sunday morning

Boulder - The Colorado Department of Transportation and its contract partner, ACME Concrete Paving Inc., will continue weekend closures on Colorado Highway 157 for concrete rehabilitation operations. Motorists traveling southbound on CO 157 (Foothills Parkway) should plan for a full roadway closure between Valmont Road and Pearl Street throughout the weekend.

Full closures are needed during concrete panel replacements to maintain the safety of motorists and the project team. Weekend operations allow for speedy progress while decreasing interruptions to weekday travelers and commuters.
