Rock slide closes highway
February 22, 2016
Traffic on a stretch of a key east-west highway in Colorado won't be back to normal for weeks. This is after boulders the size of small cars crashed onto the roadway. Workers were still finding large amounts of loose rock days after the initial slide.
The slide happened Feb. 15 on Interstate 70. The site is about 125 miles east of the Utah border. It damaged a tractor-trailer but caused no injuries. The highway was shut down in both directions, from Glenwood Springs in the west to Gypsum in the east. That forced travelers to take detours of up to four hours. The four-lane stretch carries a daily average of 300 vehicles per hour through the canyon, Colorado Department of Transportation spokeswoman Amy Ford said.
Ford advised travelers to check the transportation department website for proper routes. There were reports that some drivers used maps and GPS devices to find their own way around the slide. Some motorists ended up on mountain passes usually closed during the winter.
Hundreds of cars and several tractor-trailers lined up at a gate closing one of those passes, the Post Independent newspaper in Glenwood Springs reported.
Pitkin County sheriff's Deputy Marcin Debski directed traffic at Independence Pass in Aspen. He said he had "never seen anything like it."
Tumbling rocks have closed the stretch of I-70 several times in the past. A 2010 rock slide tore gaping holes in an elevated section of the road. The holes closed the canyon for nearly four days. That caused food shortages because delivery trucks were not able to reach restaurants and grocery stores.
In 2004, more than three dozen boulders landed on the highway. A slide in 1995 killed three people. And a boulder crashed onto a pickup truck in 1985. It critically injured a 5-year-old boy.
The CDOT said the Glenwood canyon is among 750 areas prone to slides that it closely monitors. Slides are particularly common when cold periods are followed by warm spells. When that happens, ice begins to melt.
The state spends some $8.5 million dollars a year on work to prevent and respond to rock falls across Colorado, CDOT officials said.

Why are detours measured in hours?
