Economic Impact

Shipping supports a vibrant economy.

Transportation is strategically vital to economic development. Waterborne transportation is the safest, most fuel efficient, cost-effective and environmentally responsible mode of moving goods in our global economy. Maritime’s inherent efficiencies are critical to the success of supply chain managers worldwide. The Great Lakes-St. Lawrence Seaway not only saves users billions of dollars in transportation costs each year, it also relieves pressure on the nation’s congested roads and rail lines.

Shared by two cities and two states, the Port of Duluth-Superior has been the backbone of this region’s economy for well over a century.
