Periodic traffic stops planned for rock scaling on I-70 just east of Dumont in the mountain corridor

News Release

May 20, 2021 - Central/Eastern Colorado - I-70 drivers should plan for delays

Clear Creek County ― Traffic will be periodically stopped in both directions on I-70 near Mile Point 236 just east of Dumont between the hours of 9 a.m. and 3 p.m.  Tuesday, May 25, and Wednesday, May 26.  Traffic stops are necessary while loose rocks are pushed off the mountain slope above the highway. 

Vehicles will be stopped for about 20 minutes while crews perform this rock scaling work and clean up the highway. The queue of stopped vehicles will then be released before traffic is again stopped and the process repeats. Drivers should plan for delays of up to 30 minutes.

There will be no traffic impacts during the Memorial Day holiday but another two days of brief traffic holds will take place in June when a helicopter is used to drape the rockfall mesh over the slope. Work is planned to be complete before the Fourth of July holiday. 

This rockfall mitigation work will help stabilize the slope where a 2019 rockslide the day after Thanksgiving prompted an emergency closure of I-70.

The schedule is subject to change depending on the weather and other unforeseen circumstances.
