I-270 York Street Bridge Preventative Maintenance

About the Project

Starting early December 2024, the Colorado Department of Transportation (CDOT) and contractor Structures, Inc. will begin repairs on the I-270 York Street bridge in Commerce City. The bridge deck will be replaced and resurfaced to significantly improve its safety and condition until a full replacement can be completed as part of the I-270 Corridor Improvements project.

To avoid unexpected emergency repairs, CDOT has identified specific areas needing bridge deck replacement, concrete panel repairs, and asphalt replacement within the work zone. The project will replace old asphalt with reinforced concrete to create a more durable driving surface, helping to prevent future unplanned lane closures due to emergency pavement issues. Work on this project is scheduled for completion in early February 2025.
