A cantilever spar cable-stayed bridge is a modern variation of the cable-stayed bridge. This design has been pioneered by the structural engineer Santiago Calatrava in 1992 with the Puente del Alamillo in Seville, Spain. The Hassfurt Bridge spans the Main River in Germany and has a central span of 38 meters (124 feet), considered the first contemporary cantilever bridge.
