Road Construction Alert
Road construction has begun on the section of Arapahoe Road in front of the Foothills Hospital campus and is expected to continue for several months. This may impact traffic flow and cause travel delays for patients and visitors.
At times, road closures and detours may be in effect. We recommend checking your route in advance and allowing extra travel time to ensure timely arrival for your appointment.
We appreciate your understanding and will provide updates as they become available. For additional information, you can visit the Colorado Department of Transportation’s website by clicking the button below.
About the Project
The Colorado Department of Transportation will begin resurfacing Colorado Highway 7 (Arapahoe Avenue) starting at Cherryvale Road and extending west to 28th Street in Boulder.
Work on this project is scheduled for completion in late December 2025.
The existing asphalt will be milled and overlayed with new asphalt. Milling removes the worn-out surface layer, and the fresh asphalt overlay restores the road's smoothness and improves safety. While work is in progress, erosion control measures will be in place to prevent sediment runoff and protect water resources during construction.
Work also includes Americans with Disabilities Act upgrades that include curb ramp installations. ADA curb ramps are a small but important part of making sidewalks, street crossings, and other pedestrian routes accessible to everyone.
Additionally, the City of Boulder will coordinate with CDOT to launch the East Arapahoe Bus and Turn Lanes Signing & Striping Project, which will convert underutilized right through-lanes into shared curbside lanes for buses and right-turning vehicles only, which will provide improved trip reliability for the existing bus service routes. This joint effort will help reduce costs, shorten construction timelines and lessen disruptions for the community.
The combined project between the City of Boulder and CDOT will provide improved ADA and safer connections to the corridor and bus service, as well as necessary safety and riding surface improvements for all modes utilizing the corridor.
