Westbound I-70 to close for continued rockfall mitigation
CLEAR CREEK COUNTY – Monday night, the Colorado Department of Transportation (CDOT) will continue rockfall mitigation efforts along I-70 just west of Idaho Springs at the site of this past weekend’s rockslides.-
Starting at 9 p.m. Monday, westbound I-70 will be completely closed to traffic from west Idaho Springs to Dumont.-
Traffic will be detoured off the highway at exit #239, directed onto the south frontage road and back onto westbound I-70 at exit #235.-
Westbound I-70 will remain closed overnight until crews are able to blast the rock face in the early morning at first light.- The blasting is necessary to bring down any remaining loose rock.-
Also during this time, eastbound I-70 may be stopped periodically overnight for rock scaling as necessary for the safety of motorists.- At the time of the blast, the highway will be closed to all traffic in both directions.-
The detour frontage road will also be closed during the blast.- Delays should be expected for I-70 travelers through Tuesday morning and alternate routes are advised for westbound traffic after 9 p.m. tonight.
Currently, a large crane is en route to the rockslide site.- Once the crane is assembled, it will be used to lift crews so that they can scale and drill in preparation for the morning blast.- At least 18 holes will be drilled into the rock, four to five feet deep.
After the blast, crews will remove any rock from the roadway and reevaluate the site to ensure its stability prior to opening the road to traffic.- Eastbound I-70 will likely open shortly after the blast and CDOT hopes to have westbound I-70 open soon after in the morning hours.
CDOT wants to thank motorists and nearby residents for their patience during this emergency.- As soon as CDOT engineers and geologists determine the highway is safe for travel, it will again open to traffic.- Still, I-70 drivers are urged to watch for rocks on the road when driving in Colorado’s High Country.
