CDOT Works To Prevent Rock Slides Along I-70

GEORGETOWN, Colo. (CBS4) ―
All the freezing and thawing and moisture this week has increased the danger of rock slides. CDOT worked Thursday to try to ease the threat along Interstate 70 near Georgetown.
In helicopters in the sky and on the hills above I-70 crews worked to keep traffic flowing all summer.
"We feel like this will stop most any normal size four or five foot rock from ever getting on the highway," says CDOT's Jim Pitkin.
It's mud season in Colorado, a time with the state's rocky hill sides can come tumbling down.
"With all the moisture we've been having lately, this is the time of year that we start moving a lot of rocks," says project engineer Jim Van Dyne.
Two rocks the size of cars came down in Lions from last week's blizzard. There are potential rock fall problems all over the mountains.
"McClure Pass is one," says Van Dyne. "Highway 6 there's some areas that we need to be concerned about, some of the canyons on the Front Range."
Nearly a third of CDOT's rock fall budget is being spent at Georgetown Hill. Crews hope their work will slow down up to five feet wide from crashing down onto the highway.
"We'll have 5 fences between the top of the hill and the bottom when we finish," says Pitkin.
