The Duluth Ship Canal is a vital waterway located in Duluth, Minnesota, connecting Lake Superior to the Duluth Harbor. This canal allows large ships to navigate between the lake and the harbor, facilitating the transport of goods and materials. It plays a crucial role in the shipping industry, particularly for bulk commodities like iron ore and grain. Constructed in the late 19th century, the canal features a series of locks that help manage water levels and accommodate vessels of various sizes. The Aerial Lift Bridge, a notable landmark, spans the canal and raises to allow ships to pass through. This infrastructure supports both commercial shipping and recreational boating activities.
