‘5 truck-sized boulders’; Major rockslide forces detour on Highway 119 in Boulder Canyon


BOULDER COUNTY, Colo. (KDVR) — A large rockslide occurred on Highway 119 around Mile Point 32 on Tuesday night, which included five truck-sized boulders. The area is closed from Mile Point 26-41 while crews work to clear the slide.

The rockslide happened during heavy rainfall and snow in the area known as the, ‘Narrows.’ Nobody was injured and no vehicles were damaged in the slide.

There is a northern detour at Colorado Highway 72 to Lefthand Canyon Dr. and a southern detour at Colorado Highway 72 S.

The closure is expected to last well into Wednesday.

CDOT said most of the larger rocks will need to be blasted and, because the area is very narrow, all of the material will need to be hauled away instead of just being pushed out of the way.

From the initial assessment, it appears there was damage to the roadway, so paving work will have to be done after the rocks are removed.
