Longest Bridges in South Dakota

The longest bridge in South Dakota spans 5655.5 feet. The table below ranks the state's bridges by total structure length — from major river crossings and causeway spans to long highway overpasses.

How this ranking works

Length comes from the NBI structure length field and is shown in feet. It is best read as a scale and maintenance-complexity signal, not by itself as a safety signal.
