Duluth-Superior Harbor will be dredged by Wisconsin firm

Detroit District
Published July 11, 2018

DETROIT – The U.S. Army Corps of Engineers, Detroit District, awards a contract for dredging at Duluth-Superior Harbor in western Lake Superior on the Minnesota-Wisconsin border.

The $1,933,500 contract was awarded to Roen Salvage Co., from Sturgeon Bay, Wis. The firm will dredge approximately 150,000 cubic yards of material from the harbor and deposit the dredged material at the 40th Avenue West placement site, 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. For more details, contact Lynn Rose, public affairs director, 313-226-4680, or Melissa Bosman, project manager, 313-226-7855.
