Colorado Department of Transportation crews have been working from daylight to dark in an effort to clear the way for an on-target opening of Independence Pass at 2 p.m. on Thursday, just in time for the Memorial Day weekend crowds.
However, avalanche control work was completed just last week as it was the first time weather permitted crews to get to the areas requiring a control mission, CDOT said Tuesday.
Independence Pass is a scenic stretch of Highway 82 that links Aspen to Twin Lakes. It typically opens in time for Memorial Day weekend and usually closes some time in October because of snowy conditions.
CDOT crews work with the Colorado Avalanche Information Center to clear up to one dozen slide paths that can impact the road. Not all of the paths present a threat each spring; however, according to the most recent CAIC report by area forecaster Rob Hunker, snowpack on the pass today is at 198 percent of an average year.
With the avalanche control mission completed, crews on the ground must now address the task of clearing the snow that came down the avalanche slide paths. Necessary work to open the gates may include clearing the avalanche slide paths (up to 12 total), clearing snow, ice and other debris from the roadway and shoulders and hauling out loads of rock debris from the ditches.
Crews will also need to blade asphalt millings on the shoulders to reset barriers and replace any barriers that may have been damaged. They’ll also repair or replace damaged signs, guardrails and roadside delineators, as well as patch pot holes and trim overgrown and damaged trees and brush.
“The most time-consuming of our spring activities is clearing the roadway of all the hard snow, ice and debris that can be brought down with avalanche mitigation,” said Marc Quintana, who supervises CDOT crews. “Once we clear the highway and ensure the safety of the slide paths, any repair work can begin.”
