The Claude Turner design for the original Aerial Bridge from 1901. Many companies and designers vied for this project. The bridge was built in 1904-1905. This drawing shows the spires and steel structural detail as well as the concrete footings and dimensions. Both towers are shown with an end view. In 1929 the suspended car transfer was eliminated and a lift span was installed.

Detailed drawing of the suspended car, or gondola, and the vertical structure that holds it. This is the element that moves from one side of the bridge to the other above the canal. This transfer car could hold vehicles and people. Normal speed of the car was 4 miles per hour; it made the trip in about 1 minute. This drawing includes dimensions of individual structural elements such as braces. Drawing 160, Sheet M4. Turner is identified as engineer, 816 Phoenix Building Duluth.

Ore boat leaving Duluth. Detroit Publishing Co. was a prolific post card publisher, especially in the U.S. Their cards were published from 1898 to 1933. Using a color process called Phostint, their cards were considered to be very artistic. The hobby of collecting post cards is called deltiology. The first post card was issued by the Austrian government, America's first postcards came out in 1873. Picture postcards were introduced later. The golden age of postcards was supposed to date from 1907 through the first World War.

Whaleback is an unusual ship design with steel hulls (body of the vessel) and rounded decks (boat, hurricane, main -which is the lowest full-length deck in a ship's hull, and spar are all decks at different levels) which was introduced by the inventor Captain Alexander McDougall of Duluth in 1888. It was a very stable vessel. American Steel Barge Company, a New York corporation engaged in shipbuilding and transportation on the Great Lakes as well as on the Atlantic and Pacific coasts, purchased all of the patents for McDougalls whaleback vessels for $25,000. The only remaining whaleback is the Meteor, which is now a museum at Barker's Island in Superior, Wisconsin.

View of the collapsed bridge after the well-drillling rig broke through while crossing on April 18, 1914. Notice the horse and wagon in the river. A few days before this, Marie Binger Bailey's uncle, Bernard Binger, had crossed the bridge with two loads of lumber. His daughter wrote: "The Angels are here."
In 1893, James J. Hill's Northern Steamship Company built 385-foot ocean style passenger steamers. In 1911, the peak year, 80,000 passengers traveled to Lake Superior. After 1920, the number of passenger cruise ships diminished with the advent of "motor-cars." Very few cruise ships were still in service after World War II. The Canadian steel steamer Huronic was constructed in Collingwood, Ontario, in 1902. She ran on the Northern Navigation Division of the Canadian Steamship Company, on cruise trips from Detroit to Duluth. In 1940, the Huronic was dismantled and made into a package freighter.

Marine Iron and Shipbuilding Company launches including one named Prairie State. During WWII, the company installed the piping in 30 vessels built by Zenith Dredge company of Duluth. A tugboat (tug) is a boat that maneuvers vessels by pushing or towing them. Tugs move vessels that either should not move themselves, such as ships in a crowded harbor or a narrow canal, or those that cannot move themselves alone, such as barges or disabled ships. The company was located at Eleventh Avenue West and bayfront. The company became Modern Constructors, Marine Iron and Shipbuilding in 1954. Today, Marine Iron and Shipbuilding is at 325 South Lake Avenue and Waterfront Plaza Building. Above the tug on the left, just above the tug's name, is the two story brick Webster elementary school at 433 South First Avenue East in Canal Park. It was built in 1897 and razed in 1930. It was named for Daniel Webster who, as Secretary of State, negotiated the Webster-Ashburton Treaty that established the definitive eastern border between the United States and Canada.
