The Duluth Aerial Lift Bridge is a span configuration bascule lift bridge built 1901–1905 and modified in 1929. It is located on Lake Avenue and crosses the Duluth Ship Channel, which connects the city of Duluth to Minnesota Point. The bridge was designed by Thomas F. McGilvray and C.A.P. Turner and built by the Modern Steel Structural Company. The bridge is significant as a rare type of bridge construction and as a resource in the Duluth Ship Channel Historic District.
