CO 7 (Upper) Estes Park to Raymond

About the Project

On July 5, 2016, crews kicked off phase I of the construction to improve CO 7, with an anticipated completion in September 2017. This window included a winter work stop from Nov. 15 to March 15.

The first phase included installing more than 20 culverts to carry water under the road, reconstruction to the shoulders, rock scaling, slope stabilization and asphalt paving. 

By the winter shutdown in November 2016, crews had completed 85 percent of the culverts, the bridge deck rehabilitation, construction on the business loop and the rock scaling along CO 7.

Phase two repairs started in July 2017 under a separate contract, and involve continued culvert work and roadway paving to the junction with US 36 in Estes Park.


  • Introduce certain betterments to damaged roadway facilities and make them more resilient to similar storm events in the future.
  •  Design elements—based on analysis of the flood damage—will help prevent or lessen the severe damage that significant flood events can cause.
  • At the Cabin Creek site near St. Malo, a debris/sediment basin may be installed upstream of the culvert under CO 7 to help contain large debris loads.
  • Crews will build an optional bridge over the Cabin Creek crossing to help pass debris and sediment. 
  • Re-paving and re-evaluating the drainage structures along the corridor will ensure a level of safety and provide resiliency to future storm events.
