GLENWOOD SPRINGS, Colo. (KDVR) — Glenwood Canyon is once again shut down while Colorado Department of Transportation crews work to clear mudslides in the area of the Grizzly Creek fire burn scar.

CDOT said there is currently no timetable for reopening the major highway, as Interstate 70 remains shut down in both directions between Exit 116 in Glenwood Springs to Exit 133 in Dotsero.

A spokesperson was optimistic they may have more news on when they can reopen the westbound lanes on Friday.

Crews are having issues with three drainage systems along the corridor, including one that is clogged. But the big challenge that could have long-term impact on the highway’s infrastructure is a pile of debris that has piled up near the eastbound lane, causing the Colorado River to divert and flow over the bike path and along the road.

“Due to the fact that the majority of the water is traveling up against the interstate as you can see, we have some scour concerns with that,” said CDOT’s Regional Transportation Director Mike Goolsby. “We don’t know if it’s undercutting the road or not, and through our engineering staff we have deemed that until we can get in there and look at it, it is not safe.”

Crews are working to create a safety barrier to stop mudslides along the eastbound lanes at mile point 124. Crews are also working to clear a box culvert full of material that is stopping flood waters from draining at mile point 129.
