On Thursday, Sept. 10, State Highway 133 between MM 24 and 25.5, will be closed for five hours for rockfall work, weather permitting. The full closures will be in effect from 11 a.m. to 4 p.m. Traffic must be held during this safety-critical rockfall work. During full closures, crews will perform trim blasting operations, which include both loading and detonating controlled explosives. Once the blasting is complete, additional scaling and cleanup are required before the highway can reopen under single-lane alternating traffic conditions.

Additional five-hour blast closures are anticipated on Sept. 14 and 17. Closure dates will be indicated on variable message boards along the corridor, www.cotrip.org and the project hotline in advance of the work. CDOT is coordinating with emergency first responders and urges motorists to plan alternate routes during full closures.

CR 12, which provides access to Crested Butte over Kebler Pass, will only be accessible from the south side of the work zone via Somerset during full closures. Flaggers will be present at the SH 133/CR 12 intersection to maintain access south of the work zone when full closures are in place.

Kissner General Contractors, Inc., has been contracted by the Colorado Department of Transportation to perform rockfall mitigation along an 11.5-mile work zone adjacent to the south end of Paonia Reservoir.

This project will reduce the risk of rockfall in the area, as well as provide measures to capture some material in the event of rockfall. Work includes performing trim blasting, rock scaling and rock reinforcement. Crews will install anchored wire mesh, a ground nailed wall, ditch improvements and erosion control.

The project is now anticipated to be complete in December 2015.
