Glenwood Springs Post Independent An aerial view of the debris flow currently blocking the Colorado River through Glenwood Canyon. Courtesy of Colorado Department of Transportation Interstate 70 through Glenwood Canyon is expected to remain closed due to potential structure damage underneath the eastbound lanes. Westbound lanes are currently blocked from a debris flow. A structural assessment cannot be completed before crews can cut a channel for displaced Colorado River water to flow away from the interstate, CDOT’s Region 3 Director Mike Goolsby explained. Depending on the extent of damage, eastbound I-70 will remain closed for repairs to ensure it is safe for motorists.
