Rockfall mitigation projects begin Monday

THERMOPOLIS — A three-location $664,000 rockfall mitigation project is scheduled to begin at a pair of locations on Monday, Nov. 18, with rock scaling, rock removal and repair of the existing rockfall fence west of Cody alongside U.S. 14/16/20, and rock scaling on U.S. 20/Wyoming 789 in Wind River Canyon.

Grading, rockfall mitigation and other work are scheduled at three locations: U.S. 20/WY789 between Shoshoni and Thermopolis (milepost 120.6, about 12 miles south of Thermopolis) in Wind River Canyon, Wyoming 296 (Chief Joseph Scenic Highway (milepost 35.6, about 11 miles west of WY296’s junction with WY120), and U.S. 14/16/20 (milepost 44.58, about seven miles west of Cody) west of Cody.

Wyoming Department of Transportation resident engineer Todd Frost said, “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. During the remainder of the time, motorists can expect delays of up to 20 minutes,” he said.

Work is also scheduled to begin Nov. 18 on rockfall mitigation on U.S. 20/Wyoming 789 in Wind River Canyon.

“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, 2020.

Wyoming 296 rockfall mitigation work is tentatively scheduled for the spring of 2020. “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 Wyoming 296 work is scheduled to be completed by early June.

Contract completion on the three projects is June 30, 2020.
