Wisconsin Relies on Great Lakes-Seaway Shipping
The state of Wisconsin borders 1,017 miles of Lake Superior and Lake Michigan. Its seven deep-draft commercial ports handle more than 42 million tons of inbound and outbound cargo annually.
Great Lakes-Seaway shipping is critical to the state’s manufacturing, energy and agricultural sectors. For example, farm products from the upper Midwest are loaded on vessels in Superior destined for export markets. Mining equipment manufactured in Wisconsin is moved to customers in Canada, Russia and South Africa from the Port of Milwaukee. Low-sulfur coal mined in Montana, Wyoming and Colorado is railed to Superior where vessels load it for delivery to electric utilities in the lower Lakes. Similarly, iron ore from nearby Minnesota fills gigantic lake vessels in Superior destined for steel mills in Gary, Detroit, and Cleveland. Raw materials such as sand, gravel, and salt each move through Wisconsin ports - each playing an important role in the state's economy.
Wisconsin is also home to three large shipyards that collectively have more than 2,200 employees and an annual payroll that tops $107 million. The yards build and maintain both commercial and military vessels.
