I-70 De Beque Canyon rockslide site to remain closed overnight for mitigation tomorrow

May 5, 2019 - Northwestern Colorado - Colorado Highway 65 to De Beque Cutoff Road will serve as detour route

MESA COUNTY – The Colorado Department of Transportation Geohazards team has determined, in the interest of safety, to keep eastbound I-70 at mile point 57 where a rockslide occurred earlier today closed for mitigation starting tomorrow morning. The location of the rockslide is eight miles east of Exit 49 the turnoff for CO 65 on the Grand Mesa (please see attached map). Only the eastbound lanes of I-70 are impacted.

Contractor Rock Solid, Inc. out of Grand Junction will mobilize a crane and crew to the scene at daybreak to continue evaluating the operation. Once the team has had a chance to assess, CDOT will have a better sense of how long the mitigation efforts may take.

“It’s prudent to err on the side of caution when it comes to rockfall mitigation,” said CDOT Executive Director Shoshana Lew. “We appreciate motorists taking it slow and planning ahead for the increase in travel time on the detour route.”
