A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end (called cantilevers).For small footbridges, the cantilevers may 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 prestressed concrete.
In cantilever bridges, the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The Forth Bridge in Scotland is an example of a cantilever truss bridge. A cantilever in a traditionally timber framed building is called a jetty or forebay.
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.
Cantilever bridge: Cantilever bridges are built using cantilevers—horizontal beams supported on only one end. Most cantilever bridges use a pair of continuous spans that extend from opposite sides of the supporting piers to meet at the center of the obstacle the bridge crosses. Cantilever bridges are constructed using much the same materials ...
A bascule bridge (also referred to as a drawbridge or a lifting bridge) is a moveable bridge with a counterweight that continuously balances a span, or leaf, throughout its upward swing to provide clearance for boat traffic. It may be single- or double-leafed.

The main towers of the cantilever section were fabricated off-site and moved to the bridge site in four sections. Work on the cantilever arms moved out in both directions from the tower, with the shoreward arm keeping slightly ahead of the center arm so that it would rest on a temporary support structure to stabilize the bridge.
The suspension bridge's architecture is better at handling the load in the middle of the bridge, while the cable stayed bridge is better suited to handle the load closest to the tower. Combining these two architectural engineering ideas into a hybrid has been done in Istanbul with the Yavuz Sultan Selim Bridge .
