A bridge is a structure that provides a
continuous path or road over water, valleys,
ravines, or above other roads. The basic
designs and composites of these are based on
the way they bear the weight of the structure
and its load. Beam, or girder, bridges are
supported at each end by the ground with the
weight thrusting downwards. Cantilever
bridges are a complex form of girder.
Arch bridges thrust outwards but downwards
at their ends. Suspension bridges use cables
under tension to pull inwards against
anchorages on either side of the span, so
that the roadway hangs from the main cables
by the network of vertical cables.
The cable stayed bridge relies on diagonal
cables connected directly between the bridge
deck and supporting towers at each end.
