What is a bridge? • Bridge is a structure built to span a valley, road, river, body of water, or any other physical obstacle. • Designs of bridges will vary depending on the function of the bridge and the nature of the area where the bridge is to be constructed.
Types of Bridges There are six main types of bridges: • beam bridges, • cantilever bridges, • arch bridges, • suspension bridges, • cable-stayed bridges and • truss bridges
Beam Bridge • The beam is one of the simplest forms of bridge. East India Beam footbridge
Cantilever Bridge • A cantilever bridge is a bridge built using cantilevers: structures that project horizontally into space, supported on only one end.
ARCH Bridge • Arches are used in bridges in different ways, depending on whether they are made of steel, brick or stone. The arch takes (transmits) the load from the deck of the bridge to the land on both sides.

Suspension Bridge • A suspension bridge works by hanging (suspending) the deck of the bridge from flexible chains or ropes.
Cable Stayed Bridge • The cable stayed bridge is newer than the other types of bridge. Large upright steel supports are used to transmit the load into the ground. The Bob Graham Sunshine Skyway Bridge, USA

Truss Bridge • A truss bridge is a bridge composed of connected elements (typically straight) which may be stressed from tension, compression, or sometimes both in response to dynamic loads. Truss bridges are one of the oldest types of modern bridges.
