The Meridian Highway Bridge connects Yankton, South Dakota with rural Cedar County, Nebraska.

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.
