February 10 Public Meeting Recap

The project team hosted a Virtual Public Meeting in February 2021 to let people know the project is starting and explain the scope and schedule. Visit the Public Meeting Page to review the presentation, materials, and answers to the questions that were asked during the meeting.

About the Project

In September 2013, flood waters saturated the mountainous terrain of Colorado Highway 7 (CO 7), causing numerous material slides, ditch damage and erosion to the roadway embankment. After eroding the highway embankment, the floods washed out the road in several places. Large amounts of debris, rock, and sediment were deposited in the creek and, as a result, redirected water flows – further contributing to the erosion of the channel banks and the undermining of the highway.

By November 2013, crews had completed extensive emergency repairs, including:

  • repairing full-width roadway losses;
  • repairing embankments;
  • removing sediment and debris;
  • replacing overtopped road sections
  • repairing shoulders;
  • regrading ditches; and
  • replacing damaged culverts.

Project Facts

  • Cost: TBD.
  • Contractor: Kiewit Infrastructure Co.
  • Timeline: Construction is expected to begin in Fall 2021.
  • Location: Colorado Highway 7 between Lyons and Raymond.

To learn more about the specific scope planned as part of this project, please review this GIS map. This map contains geospatial data related to hydraulic, geomorphic, roadway, and geotechnical engineering services in the Colorado Highway 7 (Lower) canyon between MP 19 and 33. All information shown is preliminary.

Project Purpose - Permanent Repairs

The Colorado Highway 7 Project will provide longer-term improvements along Colorado Highway 7 between Lyons and Raymond. Pending funding availability, improvements may include: 

  • removing and replacing temporary asphalt placed during emergency repairs;
  • adding shoulders and rockfall ditches;
  • restoring ecological systems along the corridor;
  • re-establishing the creek channel while protecting its banks; and
  • establishing topsoil and vegetation in areas that were either damaged or disturbed by emergency repair work.


Construction is expected to begin in Fall 2021, and local communities can expect the next public meeting in Summer 2021.
