KEYSTONE, Colo. - CDOT workers doing avalanche mitigation work triggered a big slide Tuesday morning that blocked U.S. 6, one mile west of Arapahoe Basin Ski Area.
Crews had the highway reopened before 1:30 p.m., said Crystal Morgan, spokeswoman for the Colorado Department of Transportation. Chains are required on all one-drive axle combo commercial vehicles; chains or snow tires all other commercial vehicles going over Loveland Pass.
It was hard work clearing the earlier slide, which was 100-feet wide and 20-feet deep, because the debris included rocks and trees, she said.
The slide delayed the morning opening of Arapahoe Basin, which was open at 1:10 p.m.
Meanwhile, U.S. 6 at Loveland Pass has been closed since Friday night by adverse weather. Morgan said CDOT crews also did avalanche mitigation work on on Loveland Pass Tuesday morning that triggered some small slides. There's no estimate on when the pass will reopen.
"This winter is the most mitigation we've done since 1987," Morgan said. "They're getting some awesome powder up there, but it results in some high avalanche threats."
Besides U.S. 6, CDOT was doing avalanche mitigation work Tuesday on Interstate 70, Berthoud Pass, Officers Gulch.
