Business relies on a thriving port.

Duluth-Superior is a port community and maritime trade is essential to its economy. While visitors enjoy seeing ships pass through the canal and under the lift bridge, those who live and work here know that every vessel supports business throughout the entire supply chain. The port is an important component of our past, present and future, and the Duluth Seaway Port Authority is proud of our role in bringing business to the port and economic development to the region.
