PLEASE PRACTICE RESPONSIBLE RECREATION IN CLEAR CREEK CANYON!

  • Whether you are climbing, biking, hiking, or paddling please practice responsible recreation in Clear Creek Canyon! Help keep the canyon safe by following these guidelines:
  • Shoulder parking is prohibited between tunnels 5 and 6 on US 6 at all times. We ask that everyone please keep the cones in place. It is unsafe for anyone outside of the project teams to move the cones around. Cars are at risk of being ticketed or towed if parked in the "No Parking Area"
  • Walking through the tunnel is prohibited. This is not safe as there isn't a designated place for people to walk in the tunnels.
    When utilizing Clear Creek, rafts and kayaks are prohibited from entering or exiting the creek inside of a construction area as there may be heavy machinery present. Please stay inside of your raft when traveling through a construction zone. There will be signage facing Clear Creek for rafters to utilize.
  • CDOT staff and Colorado State Patrol will be present throughout the day as a resource.
    We understand the projects are impacting highly sought-after outdoor recreation areas, but these impacts along Clear Creek Canyon are temporary, and the quicker our crews can complete work the quicker the projects will wrap up and the area will be fully accessible again. We would appreciate your help by using responsible recreation in the canyon.

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.
