A $664,000 rockfall mitigation project will span three locations in Wyoming. The project is scheduled to begin Monday with rock scaling, rock removal and repair of the existing rockfall fence west of Cody alongside U.S. Highway 14/16/20, and rock scaling in the Wind River Canyon.
Grading, rockfall mitigation and other work are scheduled at three locations:
• U.S. Highway 20/Wyo. Highway 789 between Shoshoni and Thermopolis (milepost 120.6, about 12 miles south of Thermopolis) in Wind River Canyon
• Wyo. Highway 296 (Chief Joseph Scenic Highway) at milepost 35.6, about 11 miles west of the highway’s junction with Wyo. Highway 120
• U.S. Highway 14/16/20 at milepost 44.58, about seven miles west of Cody.
The U.S. 14/16/20 work “consists of scaling loose material, removal of rockfall debris and repair of the existing rockfall fence,” said Wyoming Department of Transportation resident engineer Todd Frost of Cody.
Prime contractor Oftedal Construction, Inc., of Casper is scheduled to begin Monday with rock scaling.
Traffic will be carried without delay through the project from 7 a.m. to 8:30 a.m. and 4:30 p.m. to 6 p.m., he said. “During the remainder of the time, motorists can expect delays of up to 20 minutes,” Frost said.
Work is also scheduled to begin Monday on rockfall mitigation in Wind River Canyon.
“This work consists of scaling large boulders above the roadway and removal of rockfall debris,” Frost said.
Scheduled work on Monday includes placement of temporary concrete barriers to protect the roadway during work operations, he said.
Frost said a 12-foot width restriction will be in place for northbound vehicles during this project.
“Motorists can expect up to 20-minute delays during working hours, which is generally daylight until dusk,” Frost said.
The contractor is expected to work at both locations Monday through Saturday as weather allows. Digital message signs were placed last week at both locations notifying motorists of the upcoming work.
The rockfall mitigation work west of Cody and in Wind River Canyon is scheduled to be completed by Feb. 1.
Meanwhile, the Chief Joseph Scenic Highway rockfall mitigation work is tentatively scheduled for the spring.
“Work on Chief Joseph Scenic Highway consists of rockfall mesh repair including installation of four new grouted anchors and taglines in Paint Creek Canyon,” Frost said.
The Wyo. Highway 296 work is scheduled to be completed by early June.
Contract completion on the three projects is June 30.
