Rock-slide net being installed in Glenwood Canyon
Vail, CO Colorado
GLENWOOD CANYON – Crews are installing 14,000 square feet of wire netting meant to kick rocks in Glenwood Canyon from falling, the Colorado Department of Transportation says.
The mesh is being installed along a section of the canyon wall, near the bottom of the two chutes where rocks fell onto the interstate March 8, closing the freeway for about four days.
“The wire mesh is designed to keep smaller rocks – less than 3 feet in diameter – that may release from the talus slope above from reaching the highway,” said Ty Ortiz, a geologist with the Department of Transportation. “The goal is to reduce the chances of these smaller rock incidents. The mesh is not intended to mitigate an event like the one that occurred on March 8.”
The cost of the wire mesh installation is estimated at $300,000.
The repair work began on March 22 and is schedule for completion on or before May 15. The work is taking place between mile markers 124 and 125, just west of Hanging Lake Tunnel.
Westbound traffic is switched onto the inside eastbound lane through the work zone, separated from the single lane of eastbound traffic by a concrete barrier. Putting both directions of traffic onto the eastbound lanes is enabling the contractor to complete repairs on the concrete retaining wall and the westbound bridge deck.
While in this configuration, the speed limit for eastbound traffic will remain at the lowered 40 mph; the speed for westbound traffic will be lowered to 25 mph, however, due to the lane switches in this short section – which is approximately 1,000 feet. There is a 14-foot width restriction.
