Ports

Located on the Minnesota side of the harbor, the Duluth Seaway Port Authority is responsible for generating trade opportunities, advancing regional industrial development, and advocating for maritime industry interests in Duluth, Superior, and around the world. The Port Authority also oversees a two-phase, 365-acre industrial park called Airpark just east of the Duluth International Airport. Airpark features 40 private companies operating with about 700 employees, primarily in light manufacturing facilities.

The Port Authority facilitates Duluth Cargo Connect, a working partnership between the Port Authority and Lake Superior Warehousing. They provide seamless cargo handling, storage, distribution, and transportation logistics services for breakbulk, heavy lift, and other cargoes moving through the Port. Lake Superior Warehousing has operated the terminal and warehouses under contract with the Port Authority since 1991.
