Cantilever Bridge
In a cantilever bridge the beams are supported at one end only. The upper portion of such a beam experiences tension, which stretches the bridge material. The lower half experiences compression, tending to crush the beam. Long cantilevers are used in structures where clear space is required below, such as the cantilevers carrying a roof, or canopy, or roadway where a centre pillar would cause an obstruction. |  Cantilever Bridge
