Westbound CO 52 to close daily west of US 85, Nov. 16 to 18

Travel Advisory

Nov. 13, 2026 - Northeast Colorado - Bridge paving requires day time directional full closures

Weld County – Colorado Department of Transportation construction on Colorado Highway 52 will impact westbound travelers near US Highway 85 for two days starting Tuesday, Nov. 17.

Paving on the CO 52 bridge over the South Platte River, just west of the US 85 interchange, will require daytime full closures of westbound CO 52 from Nov. 17 to 18, from 8:30 a.m. to 5 p.m. The closure will extend approximately 1,000 feet, from just west of the southbound US 85 ramps to the Pearson Park driveway.

Eastbound CO 52 will remain open. The southbound US 85 off-ramp at CO 52 will also be open during the paving operation. All off-ramp traffic must turn left at the traffic signal onto eastbound CO 52 or continue straight to re-enter southbound US 85.

Westbound CO 52 traffic will be detoured either south on US 85 to CO 7 or north on US 85 to CO 66. Drivers are encouraged to plan ahead and use alternate routes.

This work is weather-dependent, and the schedule is subject to change. Message boards along the corridor and the project hotline, 720-743-0775, will provide the latest schedule updates.

This bridge work is part of a larger resurfacing project to improve nine miles of CO 52 between I-25 and US 85 (Mile Points 11 to 20). Resurfacing work includes replacing worn pavement in travel lanes, turn lanes and shoulders to improve driving conditions and extend the life of the roadway.

Drivers should expect possible delays Sunday through Thursday nights from 7 p.m. to 6 a.m. on CO 52 from Colorado Boulevard to US 85 for finishing work. Flaggers or uniformed traffic control officers may be present to direct traffic.

In addition to paving, project safety improvements include bridge repairs and guardrail upgrades. Construction is expected to be complete in December. All work is weather-dependent, and the construction schedule may change.

CDOT is committed to improving mobility in northeast Colorado. This project benefits the public by enhancing safety for travelers, providing a smoother driving surface and increasing the longevity of the highway.
