Earlier this month, I-70 shut down in both directions near Glenwood Springs after massive rocks, including a boulder as big as a truck, crashed onto the highway, making it unsafe. It was days before the highway reopened, and weeks later I-70 remains open only on one lane in each direction in areas where crews are working on repairs. Another scare came days ago, as another boulder fell onto Kurt Kuxhausen's car near the same area. He was driving home to Grand Junction via Denver when the 300-pound rock came crashing down, smashing the passenger window and a door, according to CBS4. "There's always a concern every time I go through there; I don't take it real lightly," he says. "I'm always pretty cautious because I know there have been some rockslides before and some fatalities, and I'm always a little leery about that canyon." About 100 feet away from the car, crews were cleaning up rock from the slide earlier this month. Flatiron Construction Corporation of Longmont has been named the contractor for the $860,000 repair job between mile markers 124 and 125, just west of the Hanging Lake Tunnel, reports The Aspen Times. Meanwhile, one Colorado Springs teenager died this weekend when the Jeep he was in rolled off I-70 after a possible tire blowout. Three other local teens were also in the vehicle, notes The Denver Post.
