Big Four Bridge at the border of Kentucky and Indiana state six-span truss top bridge

The Big Four Bridge is a six-span truss bridge that crosses the Ohio River, connecting Louisville, Kentucky, and Jeffersonville, Indiana. It was completed in 1895 and rebuilt in 1929.

It was taken out of rail service in 1968, and the original approaches that carried rail traffic onto the main spans were first removed in 1974–1975, earning the Big Four Bridge the nickname "Bridge That Goes Nowhere". It was converted to bicycle and pedestrian use in 2013.

The largest single span is 547 feet (167 m); the entire bridge spans 2,525 feet (770 m). It took its name from the defunct Cleveland, Cincinnati, Chicago and St. Louis Railway, which was nicknamed the "Big Four Railroad".
