Glenwood Canyon remains closed

GLENWOOD CANYON, Colorado – Interstate 70 through the canyon remained closed Wednesday night, following a day of rock-climbing and high-altitude blasting by workmen of the Colorado Department of Transportation.
State work crews, using a helicopter to ferry drilling equipment and a generator high up on the canyon wall, blasted free a huge boulder perched above the site of Monday’s rock fall.
Pieces of the boulder rained down on the freeway at shortly before 6 p.m., causing no further serious damage than the destruction done by the initial rock fall.
But CDOT officials decided not to try to reopen the highway, even on a limited basis of one lane in each direction, until crews have a chance to climb the canyon walls – yet again, today – and check for further hazards.
The impact of numerous large rocks and boulders, which fell from the northern canyon wall shortly after midnight on March 8, tore gaping holes in the road platform and closed the freeway in both directions.
The closure forced traffic to detour far to the north on U.S. 40 before dropping back south to the interstate.
According to CDOT spokeswoman Nancy Shanks, a team of six workers hiked 900 feet up the canyon wall on Tuesday morning, and “conducted rock scaling operations [removing loose rock material with pry bars and other equipment] until approximately 5:30 p.m.” when they were forced by darkness to suspend work.
A CDOT helicopter had reached the site by 10:40 a.m. on Wednesday, to bring drilling and blasting equipment up to workmen who had once again clambered up the steep canyon walls.
Their goal was to blast into bits a large boulder, said by Shanks to be “approximately 20 feet in diameter,” that officials worried might come loose at any time and crash down onto the freeway.
Shanks said the assessment of the canyon walls, for boulders and other potentially hazardous debris, should take place on Thursday morning.
If no further cause for alarm is found, she said, “I guess this means things look hopeful” for a quick reopening of at least one lane in each direction.
A woman commuting to work in northwest Colorado was killed Wednesday when a basketball-sized boulder fell on a car on U.S. 40, about 60 miles north of the I-70 incident, the State Patrol said.
That part of U.S. 40 is one of the detours around the I-70 rock slide, but there was no indication the woman had gone that way because of the slide.
The coroner identified her as Karen Lynn Evanoff, 55, of Craig, a passenger in the car. The unidentified driver was unhurt.
