OURAY, Colo. (AP) – Rocks continue to tumble down onto U.S. 550 south of Ouray (yoo-RAY’), and the Colorado Department of Transportation says the road will remain closed through the weekend.

CDOT says a 4-by-2-foot rock put a 6-inch hole in the road surface on Wednesday.

The closure severs the only direct route from Ouray to Silverton, normally a 70-mile drive over Red Mountain Pass. The detour, over Dallas Divide and Lizard Head Pass, adds nearly 100 miles to the trip.

CDOT says an average of 2,200 vehicles a day use Red Mountain Pass.
