Officials say a giant slab of rocks about the size of a football field came loose and crumbled into smaller pieces, punching a hole in the highway on Jan. 12.

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