CO 52 closed for several weeks between WCR 73 and 77 for bridge and road repairs

Travel Advisory

August 11, 2021 - Northeastern Colorado

WELD COUNTY –Colorado Highway 52 closed to through traffic between Weld County Road 73 and WCR 77 on Aug. 9 through early September. During the full closure, CDOT and the contractor team led by Martin Marietta will make extensive repairs to the bridge over Lost Creek and resurface CO 52 between WCR 73 and 77. 

Work involves removing and replacing portions of the 63-year-old structure. The six-mile signed detour route will direct traffic around the work zone using WCR 73, WCR 16 and WCR 77.

The bridge work is part of a larger project to resurface CO 52 near Prospect Valley. Over ten miles of CO 52 between Weld County Road 73 and WCR 95 (Mile Points 44 - 54.5) will receive a new asphalt surface. In most areas, the roadway will be rebuilt from the ground up using a method called full-depth reclamation. 

“Asphalt overlays and surface treatments have helped maintain the CO 52 since it was first paved. The corridor is now due for major work to address issues below the pavement. With full-depth reclamation, we’re able to pulverize the existing asphalt pavement in place and reuse it as part of the new and improved base layer,” said CDOT Regional Transportation Director Heather Paddock. 

This project will also repair the bridge over Kiowa Creek, upgrade guardrail, replace mailbox posts and install new roadside delineators. By the end of the year, drivers will enjoy a smoother highway with roadside safety enhancements. Project completion is anticipated in December 2021. 

Please be aware of the following conditions in the work zone between WCR 73 and WCR 95:

  • Expect various mobile construction operations Monday through Friday, 7 a.m. – 5 p.m.

  • Lane closures and traffic holds with flaggers, pilot vehicles or temporary traffic signals will be utilized

  • Vehicles will be held at intersections and driveways while equipment passes through to ensure product quality and safe operations

  • Temporary rough riding surfaces will be present until paving is finished

  • Speed limit reductions and width restrictions will be in place as needed

Construction schedules are weather-dependent and subject to change. Weekly updates are available on the project web page.
