This list of cantilever bridges ranks the world's cantilever bridges by the length of their main span. A cantilever bridge is a bridge built using cantilevers: structures that project horizontally into space, supported on only one end.
This list only includes bridges that carry automobiles or trains. It does not include suspension bridges, cable-stayed bridges, footbridges or pipeline bridges. The span must be 720 feet (220 m) or over to be included in the list.
