Concrete work on CO 52 kicks off next week for improvements between I-25 and US 85

Travel Advisory

April 9, 2026 - Northeastern Colorado - Nine miles of asphalt road resurfacing starts later this spring

Weld County – Colorado Department of Transportation construction on Colorado Highway 52 between Interstate 25 and U.S. Highway 85 will impact travelers from mid-April through December.

Starting Monday, April 13, crews will perform concrete work on CO 52 near I-25. Lane closures and traffic shifts will be in place for several weeks before work moves east on CO 52.

Starting at 5 a.m. on April 13, the westbound CO 52 left turn lane to Puritan Way will be closed for several weeks. Southbound Puritan Way will also be closed from south of CO 52 to north of Reliance Drive. Eastbound drivers will not be able to turn right from CO 52 onto Puritan Way during this work.

These 24/7 lane closures are required for crew and driver safety while the concrete medians are modified to improve intersection safety. Glacier Way, west of Puritan Way, is the suggested detour route. Northbound Puritan Way at CO 52 will remain open to all movements at the traffic signal.

This concrete work is part of a larger resurfacing project that will improve nine miles of CO 52 between I-25 and US 85 (Mile Points 11 to 20). Starting later this spring, resurfacing work will include replacing worn pavement in travel lanes, turn lanes and shoulders to improve driving conditions and extend the life of the roadway. Project safety improvements include bridge repairs and guardrail upgrades. Construction is expected to take about eight months, with completion anticipated in December 2026. 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.

Travel impacts

  • General work hours are from 7 p.m. to 6 a.m. Sunday night through Friday morning with occasional daytime lane closures, extended hours and weekend work.
  • Daytime work (6 a.m. to 6 p.m.) and 24/7 lane closures are expected on CO 52 near I-25 in April and early May. Weekend construction is expected to complete this work as quickly as possible.
  • The project may require single lane operations with flaggers alternating traffic for one direction of CO 52 at a time during bridge repairs.
  • Adjacent property access will be maintained during construction.
  • Temporary rough driving surfaces may be present during paving operations.
  • Speed limit and vehicle width restrictions will be in place as needed.
