Yankton Press & Dakotan
Meridian Bridge in its original configuration. Note the toll booth, counterweights, and decorative railings.
The bridge was built with a double deck in anticipation that the lower deck would be made available to a railroad, but the line never materialized. The double decking speaks to the optimism of the bridge company founders that they could attract a north-south rail line to Yankton. By the 1920s, however, the great era of railroad construction was over; many railroads were already contemplating abandoning unprofitable lines and consolidating parallel, competing lines.
The Meridian Highway Bridge Company agreed to sell the bridge to the City of Yankton in 1946 for $700,000. In 1953 after recouping the cost of the bridge through toll collection, the bridge was turned into a free facility and shortly thereafter taken over by the State of South Dakota. At the same time, the lower level which never materialized into a train route was converted to carry vehicular traffic, allowing one-way traffic on each of the two levels.
The vertical lift span of the bridge is based on the design originally developed by J.A.L. Waddell and John L. Harrington in 1894. Waddell and Harrington dissolved their partnership with Harrington starting a new company, Harrington, Howard and Ash, established in 1914. In January 1920, the Meridian Highway Bridge Company retained this respected firm to design the Meridian lift bridge.
The bridge has undergone several rehabilitation projects including the construction of new approach spans, deck modifications and several structural steel repairs within its 76-year life. The most significant alteration to the bridge occurred in 1983 when the bridge ceased to be movable and the operating machinery, operator’s house that was cantilevered off the northeast quadrant, and counterweights and cables were removed. The towers remain, defining what was the vertical lift span. The bridge retains its original configuration and is today distinguished as the only vertical lift span in Nebraska and South Dakota. The bridge was listed on the National Register of Historic Places in May 1993.
On October 11, 2009, the new Discovery Bridge was opened to traffic and the Meridian Bridge was closed. It is scheduled to be converted to pedestrian/bike use, but for now it remains closed to all traffic.
