CDOT to begin resurfacing and safety improvements on US 6 in Clear Creek Canyon

Travel Advisory

July 23, 2021 - Central/Eastern Colorado

JEFFERSON COUNTY — Starting next week, motorists can expect lane closures and traffic holds along US 6 in Clear Creek Canyon as the Colorado Department of Transportation and APC Construction will begin work on the US 6 Clear Creek Canyon Resurfacing and Safety Improvements project. This project will greatly improve the safety and driving conditions on this 11.37-mile stretch of US 6 by:

  • Resurfacing the entire project zone to address the severe deterioration of the pavement, leading to a smoother and safer driving experience.

  • Minor widening of the shoulders for added safety.

  • Removing and replacing all guardrail within the project limits.

  • Cleaning culverts, removing loose rocks, and installing new signage and striping to meet current standards.

Work will occur on US 6 between Colorado Highway (CO) 119 and the junction of CO 58 and 93 in Clear Creek Canyon. Work is expected to be complete by summer 2022 with a winter shutdown from December 2021 through February 2022.
