Boulder - The Colorado Department of Transportation and its contract partner, ACME Concrete Paving Inc., will continue weekend closures on northbound Colorado Highway 157 for concrete rehabilitation operations. Motorists traveling northbound on CO 157 (Foothills Parkway) should plan for a full roadway closure between Valmont Road and Colorado Highway 119 throughout the weekend.

Full roadway closures are necessary to maintain the safety of motorists and the project team while decreasing interruptions to weekday travelers and commuters.
