Road construction is underway on Arapahoe Avenue in front of the BCH Foothills Hospital campus, which also houses the Boulder Medical Center-Foothills clinic. Work is expected to continue through late December 2025 and may impact traffic flow and cause travel delays for patients and visitors.
Please Plan Ahead

About the Project
The Colorado Department of Transportation (CDOT) is resurfacing Colorado Highway 7 (Arapahoe Avenue) between Cherryvale Road and 28th Street in Boulder. The project includes:
- Milling and resurfacing of asphalt to improve road safety and ride quality
- Installation of ADA-compliant curb ramps
- Erosion control to protect nearby waterways during construction
In collaboration with the City of Boulder, CDOT will also implement the East Arapahoe Bus and Turn Lanes Signing & Striping Project, which includes:
- Converting underused traffic lanes into shared bus and right-turn lanes
- Enhancing bus route reliability and reducing community disruption
Together, these projects aim to improve accessibility, traffic flow, and safety for all travelers in the corridor.
