The view of the Aerial Lift Bridge and the canal pier’s lighthouses as we enter the Duluth Ship Canal from Lake Superior.
The Duluth Ship Canal is an artificial channel cut through Minnesota Point, providing direct access to Duluth harbor from Lake Superior. This channel is defined by a pair of breakwaters 1,720 feet long and 300 feet apart. The piers project roughly 1,150 feet beyond the shoreline and the channel is maintained at 245 feet wide and 28 feet LWD, allowing passage of ocean-going ships. Three lighthouses are placed on the sides of the channel: the Duluth North Pier Light and the Duluth South Breakwater Outer Light mark the lake ends of the channel, while the Duluth South Breakwater Inner Light functions with the south breakwater light as a range light. At the harbor end, the channel is straddled by the Aerial Lift Bridge which connects Minnesota Point to the rest of the city. There are no locks; most ships transit the channel under their own power, though tug service is available in case of adverse weather. Around a thousand vessels a year ship from the Duluth–Superior port.
