CDOT continues to assess damage after rockslide in Glenwood Canyon early this morning

February 5, 2019 - Southwestern Colorado


GARFIELD/EAGLE COUNTY -Eastbound lanes of I-70, following this morning's rockfall, are currently open but will shut down again in preparation for the staging of a crane for clean up and rockfall mitigation to begin this afternoon. Eastbound will be open again when crane is in place and initial mitigation is complete. CDOT’s hope will be to have one lane westbound open by tonight. There is no estimate on a time for a full reopening of I-70 and intermittent closures may occur as rockfall mitigation continues.  

CDOT crews have been on scene since 1:00 a.m. today after a rockslide in Glenwood Canyon. The rockslide occurred at mile point 120.5 about a half a mile west of the Grizzly Creek rest area.  Currently, CDOT maintenance, geohazard and specialized teams are working on scene.


Closure points for the incident are eastbound Exit 116/Main Glenwood Springs and westbound at Exit 133/Dotsero. Commercial Vehicle truck parking as been implemented at the Dotsero location.
