Roen Salvage Co., Sturgeon Bay, has been awarded a $1,933,500 contract by the U.S. Army Corps of Engineers, Detroit District, for dredging at Duluth-Superior Harbor in western Lake Superior on the Minnesota-Wisconsin border. The firm will dredge approximately 150,000 cubic yards of material from the harbor and deposit the dredged material at a shallow cove on the Duluth side of the harbor. The dredging will begin in August and will be complete by mid-November. “We are pleased to award this contract that will keep Duluth-Superior Harbor open to commercial shipping traffic and provide dredged material for beneficial use in the restoration of 40th Avenue West,” said Lt. Col. Dennis Sugrue, district engineer. “Duluth-Superior Harbor provides for low-cost waterborne transportation of commodities such as iron ore, coal and limestone which translates directly into more competitive American steel, lower cost energy and lower cost concrete for construction in our cities and on our highways.” The U.S. Army Corps of Engineers, Detroit District, maintains a navigation system of 91 harbors and four connecting channels, including the channels joining lakes Superior, Michigan, Huron, St. Clair and Erie.
