Types Of Bridges

Beam bridgesTruss bridgesCantilever bridgesArch bridgesSuspension bridgesDouble-decked bridges

Beam Bridge

Beam bridges are horizontal beams supported at each end by substructure units. And beams are connected across two or more spans. When there are multiple spans, the intermediate supports are known as piers.

Truss bridges

A Truss bridge is a bridge whose load bearing superstructure is composed of a truss. This truss is a structure of connected elements forming triangular units.

Cantilever bridges

Cantilever bridges are built using cantilevers horizontal beams supported on only one end.

Arch bridges

Arch bridges have abutments at each end. The weight of the bridge is thrust into the abutments at either side.

Suspension bridges

Suspension bridges are suspended from cables.

Double-decked bridges

Double-decker bridges have two levels, such as a Double Decker Bridge in Hong Kong have six lanes on their upper decks, and on their lower decks there are two lanes and a pair of tracks for MTR metro trains
