CO 7 Cherryvale Road to 28th Street Resurfacing
Expect delays on northbound CO 157 (Foothills Parkway) at CO 7 (Arapahoe Avenue) for ADA upgrades: Alternate route is advised
Monday, Aug. 4 through Friday, Aug. 8, the right lane will be closed 24/7 on Foothill Parkway (CO 157), just south and north of CO 7 (Arapahoe Avenue) for Americans with Disabilities Act curb ramp and sidewalk upgrades. Delays are expected, and an alternate route is advised. Please visit the Traffic Impacts section below for details.
About the Project
The Colorado Department of Transportation and contractor Asphalt Specialties Co. began a construction project on Colorado Highway 7 (Arapahoe Avenue) between 28th Street and extending east to Cherryvale Road in Boulder.
Work on this project is scheduled for completion in late December 2025.
The existing asphalt will be milled and overlaid 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 ADA upgrades that include curb ramp installations. These 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, and 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.
This 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. Partnering on these projects reduces the overall construction duration and impact on users in the corridor.
