CDOT Conducts Emergency Rock Scaling Project on I-70 in De Beque Canyon

Periodic 20-minute delays expected for eastbound and westbound commuters as crews work to remove loose rocks from mountainside.

Published on Feb. 9, 2026

The Colorado Department of Transportation is conducting an emergency rock scaling project in De Beque Canyon on Interstate 70 on Monday and Tuesday. The work is expected to cause periodic 20-minute delays for eastbound and westbound commuters as crews remove loose rocks from the mountainside to improve safety.

Why it matters

After a recent rockslide, a geohazard team assessed the hillside and determined that additional loose rocks posed a continued risk to the roadway. The rock scaling project is necessary to protect motorists and workers from potential rock falls and bouncing debris across the highway.

The details

The project is located on I-70 near Colorado Highway 65, where rocks have been falling from the mountainside. The work involves periodic closures in both directions to allow a contractor to remove loose rocks from the high mountain slope above the highway. This controlled process is safer than allowing the rocks to fall uncontrolled, which could potentially hit the pavement and bounce across all lanes of traffic.

  • The rock scaling project is taking place on Monday, February 10, 2026 and Tuesday, February 11, 2026.
  • Periodic 20-minute delays are expected for eastbound and westbound commuters on Interstate 70 during the project.
