CDOT begins permanent flood repairs in Coal Creek Canyon

March 15, 2019 - The project will include road repairs, culvert replacement, and adding a shoulder and guardrails

GOLDEN, CO – The Colorado Department of Transportation (CDOT) and contractor, M.A. Mortenson, will begin an important flood repair and roadway improvement project along a stretch of Coal Creek Canyon in early April 2019. The area sustained major damage from the floods of 2013.


The CO 72 Permanent Repairs project will reconstruct approximately 12 miles of CO 72 through Coal Creek Canyon heavily damaged by flooding in 2013. While emergency work repaired damages to make the roadway passable, improvements included in this project will help mitigate future flood damage and potential road closures. Specific work includes:

  • Repairing roadways with hot mix asphalt at a thickness of 4 feet
  • Replacing culverts to accommodate large storm events
  • Stabilizing slopes and restoring channels
  • Adding a 4-foot shoulder along westbound CO 72 from Plainview Road to Crescent Park


The project is located on CO 72 for 12 miles through Coal Creek Canyon from MP 24.5 to MP 12.5.


Construction on Colorado Highway 72 will impact all motorized and non-motorized traffic as the Colorado Department of Transportation improves approximately 12 miles through Coal Creek Canyon. Travel restrictions are necessary through the entire work zone between Plainview Road (MP 12.3), which is approximately 1.7 miles west of CO 93 in Jefferson County, and the community of Pinecliffe (MP 24.6) in Boulder and Gilpin Counties.

  • Lane closures and other traffic notices will be posted a week in advance on
  • The public may call the project hotline at 303.960.2825 at any time for information on the project, or for any travel impacts or access issues.


The project will kick off on April 1, 2019 and is expected to last until Dec. 2019.

  • Working hours are Mon. to Fri. 7:00 a.m. to 5:00 p.m.
  • No weekend work is expected.
  • All construction schedules in Colorado can be impacted by weather and are subject to change.
