About the Project:

The Colorado Department of Transportation will begin removing and replacing all existing tunnel lighting for Tunnels 1-3, 5, and 6 along US 6 Clear Creek Canyon between the intersection of CO 93 and; CO 58 to Interstate 70 near Idaho Springs.

The project will modernize the lighting in all five tunnels by replacing existing lighting with new LED tunnel lights, installing lane traffic control signals at the tunnel portals, and other infrastructure updates. The new lighting in the tunnels will improve safety and visibility in Clear Creek Canyon and will be more energy efficient.

Work Schedule

  • The work will be completed in two phases in Spring 2021 and Fall 2021, with a summer shutdown to accommodate seasonal motorists.

Traffic Impacts

  • Overnight full closures will be necessary to complete this work. The full closures will take place on Sunday nights from 7:00 pm to 7:00 am, and Monday through Thursday nights from 4:00 pm to 4:00 am along US 6 between I-70 and CO 119.
    • Detour: All motorists needing to get to Black Hawk or Central City during the full closures will need to access US 6 Clear Creek Canyon at the intersection of CO 93 and CO 58 to connect with CO 119.
