A $1.15 million erosion repair project is scheduled to begin Monday adjacent to the Big Wind River bridge west of Riverton on U.S. 26.
Kilroy, LLC, is the prime contractor. The Wyoming Transportation Commission awarded the contract to Kilroy in December.
“The purpose of this project is to complete a long-term project to keep the river flowing under the bridge,” said Wyoming Department of Transportation project engineer Cody Johler of Riverton. “Right now, the river is trying to flow through the bridge abutment on the northeast corner of the Big Wind River bridge.”
The project’s scope of work includes 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 will be hauled to the project site from gravel pits near Lander and Dubois, and the riverbank will be rebuilt using material hauled from a state-leased gravel pit several miles east of the work site.
Johler said U.S. 26 traffic delays will be minimal through the area.
Contract completion date is June 30, 2019.
