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.

Every student in Duluth learned about the Aerial Bridge from family or teachers. This table-top model in clay is typical in demonstrating how central to children and families the structure and impact of the bridge was and is to residents of Duluth.

Marshall-Wells Hardware merchandise is loaded and ready for delivery to various railroad lines for transport. The first horse-drawn sleigh will take the orders packed into it to the Chicago, St. Paul, Minneapolis and Omaha depot. The truck behind the sleigh is destined for the Soo Line depot. The next in line will be shipped on the Great Northern railway and the one after that will go to the Northern Pacific. The Union Depot served seven railroads including the GN and NP. It still stands as the St. Louis County Heritage and Arts Center. All of the other depots are gone. The Marshall-Wells Company started in 1886 as Chapin and Wells Company a wholesale hardware business. Albert Morley Marshall, son of Seth, bought controlling interest in 1893 and changed the name to Marshall-Wells Company. The company grew to include 14 wholesale offices throughout the northwestern U.S. and Canada. In 1955 Ambrook Industries Inc. of New York bought controlling interest. Kelley-How-Thomson and Marshall-Wells merged January 1, 1958. Kelley-How-Thomson had been a subsidiary of Marshall-Wells since 1955 when Ambrook bought Marshall-Wells and reorganized. The Coast-to-Coast Stores bought the Duluth division of Marshall-Wells-Kelley-How-Thomson Company in 1958, which ended the Duluth firm's operation. Also in the image are the People's Hotel 246 Lake Avenue South, and the Lyceum Theater billboard.

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.

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.

139-D The caption of this post card says The unique Aerial Lift Bridge and Ship Canal Entrance to Duluth-Superior Harbor is an outstanding attraction of this popular summer vacation city. Total bridge load lifted is 900 tons. Only 55 seconds are required to lift the span 135 feet. The Harbor is second only to that of New York City in shipping tonnage and through it passes about 60 per cent of America's iron ore production, from the great iron ore ranges just north of Duluth. Another fact, not included in the caption is that John H. Darling (1847-1942), U.S. Engineer for Duluth-Superior Harbor, oversaw replacement of the original wooden canal piers with concrete piers in 1897. The piers have been maintained and repaired with a major remodeling/rehabilitation in 1985-1986.

The caption for this post card says The famous Aerial Lift Bridge, at the entrance to the Duluth -Superior harbor, is the largest of its kind in the world. The 900-ton span, lifted by electrical energy stored in batteries, rises 120 feet in 50 seconds each time a boat approaches the harbor.

The parallel concrete piers jut out into the lake forming the canal leading to the harbor. Since its remodeling into a lift bridge in 1930, every vessel passes under the Aerial Lift Bridge's raised span. In this view the span is down, and traffic and people cross it as a roadbed. The South Pier is at the left, the North Pier is at the right. Minnesota Point's light sand beach draws residents and tourists in all seasons but especially throughout the summer months. The expanse of the slips and wharves of the harbor indicate an industrial scene. You can see the light road that is Skyline Parkway parallel to the horizon running the length of Duluth.
