Erosion repair project concludes Monday with seeding efforts west of Riverton near the Big Wind River bridge

A $1.15 million erosion repair project wrapped up Monday adjacent to the Big Wind River bridge west of Riverton on US 26.

Kilroy LLC, of Afton is the prime contractor. The Wyoming Transportation Commssion awarded the contract to Kilroy this past December.

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.

"This was a long-term project to keep the river flowing under the bridge," said Wyoming Department of Transportation project engineer Cody Johler of Riverton.

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 US 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.

Contract completion date is June 30, 2019.
