The Corps of Engineers’ contractor, Legacy Corporation, from East Moline, IL, will move around 50,000 cubic yards of river sand from Crater Island and place it at the Corps of Engineers-owned Brownsville Placement Site, along Highway 26.

Corps river sand managers said that the work will last through the end of July.

The work includes using heavy equipment and barges to move the river sand.

Additionally, Crater Island will be closed to the public during active work due to safety concerns.

This project is required to restore river sand storage capacity for future dredging needs, which are required to maintain the Mississippi River 9-foot navigation channel and to ensure a safe, reliable navigation system, said USACE.
