Around midnight, Sunday March 7, there was massive rockslide on I-70 in Glenwood Canyon at mile marker 125, just west of the Hanging Lake Tunnel. As of 5:00pm MST, eastbound and westbound I-70 is closed between approximately Dotsero and Glenwood Springs. One boulder is reported to be the size of a semi truck with an estimated weight of 66 tons. Major damage to the road surface was also reported. I-70 remains closed in both directions between Glenwood Springs (mm 116) and at Dotsero (mm 133). Motorists can take US 40 to SH 13 as an alternate route. US 50 to the south is now closed over Monarch pass due to adverse conditions.
Making things worse, due to adverse weather conditions, many alternate routes are closed or very dangerous. Currently, CDOT recommends motorists use US 40 to SH 13 as an alternate route.
This road closure has made travel into and out of Aspen, Colo. virtually impossible as there is simply no easy way to reach Aspen during the winter months.
