The $1.15 million erosion repair project that wrapped up in April adjacent to the Big Wind River bridge west of Riverton on U.S. 26 is working as designed and constructed.
Kilroy, LLC, of Afton is the prime contractor. Using more than 15,500 cubic yards of pit-run rocks and dirt were placed along the north side of the Big Wind River riverbank, along with more than 6,000 cubic yards of rocks, to combat future river erosion at the Big Wind River bridge.
The project’s scope of work included rebuilding and armoring the river bank upstream from the 500-foot-long bridge while completing erosion repairs near the bridge on U.S. 26 at milepost 102.81, about 30 miles west of Riverton between Diversion Dam and Pilot Butte Reservoir.
Rock was hauled to the project site from gravel pits near Lander and Dubois, and the riverbank was rebuilt using material hauled from a state-leased gravel pit several miles east of the work site.
