Postcard from the Entrance to the Duluth-Superior Harbor
This postcard of the Aerial Bridge, circa 1915-1925, notes its span is “393 feet 9 inches, 135 feet high from water line” and its construction cost was $100,000. The image shows a ferry car being transferred across the canal. The bridge’s era as a transfer bridge ran from March 27, 1905 to July 1, 1929.
