The Meridian Bridge, a landmark in Yankton since 1924, is the result of the hard work and determination of local citizens. The bridge closed to vehicle transportation in October 2008, but opened in November 2011 to foot and bike traffic. Spanning over 3,029 feet, the Meridian Bridge is the longest pedestrian bridge connecting two states: Nebraska and South Dakota. It officially opened on October 11, 1924 and was the first permanent bridge crossing the Missouri River. This unique “double-decker” bridge, where one lane is positioned above another, was constructed as a lift-span bridge to allow riverboat traffic to traverse the river. Up until 1953, it was operated as a toll bridge. For trail information, visit our trails page.
