After a crash closed the east and westbound lanes on Interstate 70 through Glenwood Canyon earlier Friday morning, the stretch of roadway is now open, the Garfield County Emergency Communications Authority announced at 4:46 p.m.

UPDATE, 2 p.m.: One lane on westbound opened around 1 p.m., but the left lane remains closed as does the entirety of westbound traffic as efforts to clear the crash and its debris continue.

Shortly before noon, a semitruck traveling westbound crossed into the eastbound lanes near Hanging Lake and is “now blocking eastbound traffic,” according to Colorado Department of Transportation spokesperson Elise Thatcher.

Colorado State Patrol Master Trooper Gary Cutler said the 39-year-old female driver of the vehicle appears to have been uninjured, despite the truck being separated from its engine and going through a barrier.

Cutler could not speak to any damages to the truck’s contents.

The crash occurred at mile marker 125 around the Hanging Lake exit. In the area, both directions of I-70 are level and separated by cement barriers and metal guard rails with an emergency turnaround space. It is unclear what barrier the truck passed through and what debris resulted.

A hazardous materials team is onsite for a fuel spill, Cutler said.

The cause of the crash is still being investigated. No timetable for the reopening of eastbound and the one remaining westbound lane was given.

An initial message from the Garfield County Emergency Communications Authority indicated that eastbound was closed at mile marker 116, the downtown Glenwood Springs exit, at 11:47 a.m.
