I-70 Rockfall Mitigation E. of Dumont

About the Project:

This rockfall mitigation work will help stabilize the slope where a 2019 rockslide the day after Thanksgiving prompted an emergency closure of I-70. Rock scaling work done immediately after this slide and rock blasting in mid-December 2019 helped stabilize the slope by removing loose material.

This follow-up work will allow crews to install the anchor bolts and cover the slope with rockfall mesh to help prevent rocks from falling onto I-70 below.

Project Facts

  • Cost: $900,000
  • Contractor: GeoStablization 
  • Timeline: May - July 2021
  • Location: I-70 just east of Dumont in Clear Creek County

Work Schedule

  • Work is expected to be complete before the Fourth of July holiday. The schedule is subject to change depending on the weather and other unforeseen circumstances.  

Traffic Impacts

  • I-70 traffic will be periodically stopped in both directions near Mile Point 236 east of Dumont for a short-term rock scaling project.
  • Tuesday, May 25, and Wednesday, May 26: Traffic stops will occur between 9 a.m. and 3 p.m. each day while loose rocks are pushed off the slope above the westbound lanes. Drivers should plan for delays of up to 30 minutes if driving through this area.
  • June: There will be another two days of brief traffic holds in June when a helicopter is used to drape the rockfall mesh over the slope.
