Skiers and others driving on Interstate 70 near Idaho Springs can expect periodic delays as Colorado Department of Transportation crews perform rockfall mitigation this month.

Some of the work will be done on rock face next to westbound I-70 near mile marker 236 just east of Dumont where two rock slides caused closure of the road last week.

The Colorado Department of Transportation will begin the work near mile marker 239 on the west end of Idaho Springs this Wednesday, Dec. 4., according to a release.

I-70 traffic will be periodically stopped in both directions between the hours of 9 a.m. and 3 p.m. on Wednesday and Thursday. Work will continue on the following Mondays through Thursdays during the weeks of Dec. 9 and Dec. 16.

Vehicles will be stopped for about 20 minutes while crews remove loose rocks and clean up the highway as part of scaling operations.

This stretch of rock wall was planned for rockfall mitigation in spring of 2020. Due to the early snow storms and extra moisture this fall, the scaling work must be done as soon as possible to prevent slides.

On Monday, Dec. 9, crews will also scale and drill the rock face next to westbound I-70 near mile marker 236, the location of last weeks rock slides.

This work will be done to prepare for blasting that is scheduled to be done during the day on Dec. 18. The interstate will be closed for a few hours in both directions during blasting in the location.

This work must be done as soon as possible to stabilize the rock face. The rock face is protected by a fence and barrier to help prevent loose rocks from spilling into the roadway.
