On Monday, July 1, 1929, the suspended car made its last trip across the canal. The bridge's modification to operate with a lift span began on April 8, 1929, with a low bid of $448,000 by the Kansas City Bridge Company. The Aerial Lift Bridge was first operated on March 19, 1930. The bridge has a clearance of 138 feet when the lift section is completely up and when down it is 16.5 feet above the water. The length of the span is 386 feet and weighs 900 tons. The distance from the water to the lower edge of the truss is 172 feet 7 inches; to the top of the truss it is 227 feet. During the shipping season it makes about 25 lifts a day. The new bridge is owned and operated by the City of Duluth on permit authorized by Congress. The Ship Canal and grounds are under the authority of the Lake Superior Area Office of the U.S. Army Corps of Engineers.
