The contracts were separately awarded to Morrish-Wallace Construction Inc., of Cheboygan, Michigan, (d.b.a.) Ryba Marine Construction. These dredging projects help maintain the Great Lakes navigational channel to keep cargo moving – products like iron ore, limestone, coal and cement.

The project (contract award number W911XK20C0006) consists of routine maintenance dredging of sand, silt and organic material from the Detroit River federal navigation channel.

The project (contract award number W911XK20C0009) will place material at Dickenson Island Confined Disposal Facility. Dredging will take place at various locations throughout the federal channel. It is scheduled to start around August 15 and complete around August 30.
