Travel Advisory

April 28, 2021 - Northeastern Colorado

BOULDER COUNTY – A major rock slide, including five truck-sized boulders, fell onto Colorado Highway 119 around Mile Point 32, closing the road for an extended period Tuesday evening. The road is closed from MP 26-41. The northern detour is CO 72 to Lefthand Canyon Drive and CO 72 south is the southern detour for the area.

The slide happened during heavy rain and snow in the area referred to as the Narrows and is not in the project area where CDOT has been doing permanent repair work from the 2013 flood. No people were injured, and no vehicles were reportedly damaged. 

Specialized rock teams will be brought in to clear the road, but it is expected the closure will be in place well into Wednesday.
