Glenwood Springs Post Independent A major debris slide partially blocks a section of the Colorado River near MM124 in Glenwood Canyon after a flash flood swept rocks and debris down the Devils Hole drainage on Thursday. Chelsea Self / Post Independent UPDATE 1:12 p.m. Saturday, July 24: Interstate 70 is now open in both directions through Glenwood Canyon. Original story: The eastbound lanes remain closed due to potential structure damage underneath the eastbound lanes. 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.
