CDOT announces June 11 to 19 closure for Santa Fe Drive to eastbound C-470 flyover bridge repairs

Travel Advisory

June 10, 2026 - Denver Metro/Central Colorado - Motorists can expect signed detours to be in place throughout the closure

Douglas County — The Colorado Department of Transportation, in partnership with Ames Construction, will close the westbound C-470 off-ramp at Santa Fe Drive and the southbound Santa Fe Drive to eastbound C-470 flyover bridge for approximately one week.

The full closure is anticipated to begin at 6 a.m. Thursday, June 11, and continue through 6 a.m. Friday, June 19. A signed detour will be in place.

The weeklong closure is necessary to allow concrete to properly cure before traffic can safely travel on the bridge. This is expected to be the final extended closure required for the broader bridge repair project.

About the Project

CDOT is completing interim repairs on the southbound Santa Fe Drive (US Highway 85) to the eastbound C-470 flyover bridge. Crews are repairing a pier cap and column at Pier 7 to help ensure the continued safety of the traveling public. Monitoring equipment remains in place and traffic control will continue while repairs are completed. The project is anticipated to be complete in fall 2026.

  • The westbound C-470 to northbound Santa Fe Drive slip ramp will remain closed for the duration of the project.
  • Additional short-term ramp and lane closures may occur as construction progresses.
  • Residents near the interchange may experience intermittent construction noise, lights and equipment activity.
  • All work and traffic impacts are weather-dependent and subject to change.
  • Overweight load restrictions will remain in place for commercial motor vehicles on the flyover ramp. Drivers should follow all posted weight-limit signage.
