The bridge crosses the Missouri River, connecting
Yankton, South Dakota to the north with
Cedar County, Nebraska to the south. Prior to the construction of the bridge, traffic moved between these two points via a
ferry service, started in 1870, and a seasonal pontoon bridge, first installed in 1890. The pontoon bridge was disassembled and rebuilt twice a year, once to float on open water, and once to be placed on solid ice. After a 1915 initiative to build a permanent bridge faltered with the U.S. entrance into
World War I, a new effort was started by the Yankton Chamber of Commerce 1919. Though fundraising problems caused a temporary halt in 1922, the new bridge, featuring a
movable span to allow for river navigation, was completed during the summer of 1924. The dedication ceremony was held on October 11, 1924, and the bridge opened as a toll bridge. It was the last link of the
Meridian Highway, which became U.S. Route 81, to be completed. It was designed for use by trains on the lower level of the bridge and vehicular traffic on the upper level; a
lift mechanism allowed river traffic to pass below. However, trains never used the lower level. In 1953, all tolls were lifted and the two levels were converted to one-way traffic: northbound on the top, southbound on the bottom. In the 1980s, the lift mechanism and counterweights were removed, and the decorative iron railings on the upper level were replaced by Jersey barricades. The bridge was added to the
National Register of Historic Places in 1993. The bridge was used as location for filming a scene of the 2016 film
Until Forever. ==Present and future use==
