Full southbound closure on CO 157 (Foothills Parkway) between Valmont and Pearl expected this weekend

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.

Southbound CO 157

  • At 7 p.m., crews will close a single lane on southbound CO 157 from Valmont Road to Pearl Street. A full southbound closure will follow at 9 p.m.
  • Southbound motorists will be detoured at the Valmont Road exit, west to 30th Street, then south to Pearl Street to the southbound CO 157 on-ramp
  • Travelers going westbound on Valmont Road to southbound CO 157 will use the same detour route. Travelers heading eastbound on Valmont Road to southbound CO 157 will be rerouted south on 47th Street to Pearl Street to the southbound on-ramp
