The Superior Union Depot or Superior station of Superior, Wisconsin was built in 1905, replacing a previous depot, which had burned down in 1904. It was built of Lake Superior brown sandstone and designed by Duluth architects German and Lignell. The depot primarily served the Great Northern Railway, Northern Pacific Railway and Duluth, South Shore and Atlantic Railway. Burlington Northern (the company absorbing the Great Northern and the Northern Pacific) ran the final passenger trains (Badger and Gopher, both to Minneapolis and St. Paul) through the station. The Northern Pacific Railway ran local unnamed service to St. Paul and Minneapolis and service to Staples, Minnesota, into the latter 1960s. Passenger service ceased upon the formation of Amtrak in 1971, but resumed between Minneapolis and Superior in 1975. Wisconsin Governor Patrick Lucey spoke at the station dedication. Superior was served by the Arrowhead and later the North Star between Chicago and Duluth. Service ceased in 1984. The depot continues to exist as a business.

The Superior Shipbuilding Company was originally called the American Steel Barge Company, and based in Duluth, Minnesota. It was founded by Scottish Captain Alexander McDougall who founded it so he could produce his new whaleback ship, this was Whaleback Barge 101. In 1900 McDougall sold his firm to the American Ship Building Company which transferred the company to Superior, Wisconsin and renamed it Superior Shipbuilding Company, also called AmShip Superior. After World War I the yard stopped manufacturing ships and instead turned to repair work. They continued repairing ships until 1945 when American Ship Building Company decided to sell it. It was initially known as the Knudsen Brothers Shipbuilding & Dry Dock Company. In 1955 it was renamed Fraser-Nelson Shipyards then Fraser Shipyards and still exists today. Fraser Shipyards does dry dock work, also conversions: steam to diesel and coal-fired to oil-burning. Lake Assault boat builders operate out of Fraser Shipyards.

SS Edward L. Ryerson is a steel-hulled American Great Lakes freighter that entered service in 1960. Built between April 1959 and January 1960 for the Inland Steel Company, she was the third of the thirteen so-called 730-class of lake freighters, each of which shared the unofficial title of "Queen of the Lakes" because of their record-breaking length. She was not only the last steam-powered freighter built on the lakes but also the last one that was not a self-unloader. Since 2009, she has been in long-term layup in Superior, Wisconsin. She is one of only two American-owned straight deck lake freighters, the other being John Sherwin, built in 1958.Built to transport iron ore almost exclusively, Edward L. Ryerson completed her sea trials on August 3, 1960. She then travelled to Escanaba, Michigan, where she loaded a cargo of iron ore, embarking on her maiden voyage for Indiana Harbor, Indiana, on August 4. The ship set a Great Lakes iron ore cargo haulage record that stood for three years on August 28, 1962, after loading 24,623 long tons (27,578 short tons; 25,018 t) of iron ore in Superior, Wisconsin. Because of her top speed of 19 mph (31 km/h), she received the nickname of "Fast Eddie". Enthusiasts consider Edward L. Ryerson to be one of the most aesthetically pleasing lake freighters ever built; she quickly became one of the most popular boats on the lakes, to the point that there were rumors that at the Soo Locks, she would regularly be directed through the lock closest to the shore, the MacArthur Lock, for the benefit of boat watchers. Because of a downturn in the steel industry, Edward L. Ryerson was laid up in Indiana Harbor for the 1986 and 1987 shipping seasons, returning to service in 1988. She was laid up for a second time in January 1994 in Sturgeon Bay, Wisconsin, where she remained inactive until April 1997. In 1998, Inland Steel was acquired by the Netherlands-based Ispat International N.V. The same year, Edward L. Ryerson was renamed Str. Edward L. Ryerson. She was sold to the Indiana Harbor Steamship Company later in 1998; she entered long-term layup at the Bay Shipbuilding Company in Sturgeon Bay in December the same year, returning to the lakes in 2006. In 2009, she entered long-term layup at the Fraser Shipyard in Superior, remaining stationary as of 2022.
