From Pathfinder Wiki
A bridge built using cantilevers, structures that project horizontally into space, supported on only one end. For small footbridges, the cantilevers my be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from pre-stressed concrete. The steel truss cantilever bridge was a major breakthrough when first put into practice, as it can span distances of over 1,500 feet, and can be more easily constructed at difficult crossings by virtue of using little or no falsework.
