Rock slide closes highway

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 first 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.  Fortunately, there were no injuries. The highway was shut down in both directions. 

The shutdown was from Glenwood Springs in the west to Gypsum in the east. That forced travelers to take detours.  Some took up to four hours. The four-lane stretch carries a daily average of 300 vehicles per hour through the canyon. That is according to Colorado Department of Transportation spokeswoman Amy Ford.
 
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. But a few motorists ended up on mountain passes. Some passes are closed during the winter.
 
Hundreds of cars and several tractor-trailers lined up at a gate closing one of those passes. That was according to the Post Independent newspaper. The paper is based in Glenwood Springs.
 
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. Those holes closed the canyon for nearly four days. The closure 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.
