Bridge:
A bridge is a structure built to span physical obstacles such as a water body, valley, or road, for the purpose of providing passage over the obstacles.

Site selection:
Site should be geologically sound. At site , the river flow should be without
whirls and cross-current. At the site , there should be suitable high
banks above high flood level on each sides.
These should be no sharp curves in the approaches.
Avoidance of excessive under water construction work.

Beam Bridge:
Beam bridges are the simplest structural forms for bridge span supported by piers. The deck can be either simply supported or continuous.They are often only used for relatively short distances

Truss Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss. These are one of the oldest types of modern bridges. This truss is a structure of connected elements forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads.

Cantilever Bridge
Cantilever bridges are built using cantilevers—horizontal beams supported on only one end. Most cantilever bridges use a pair of continuous span that extend from opposite sides of the supporting piers to meet at the center of the obstacle the bridge crosses.

Arch Bridge
It have arch-shaped structure.
It transfer the weight of the bridge and traffic loads into thrust forces into the abutments.
very good in compression

Suspension Bridge
A suspension bridge is a type of bridge in which the deck (the load-bearing portion) is hung below suspension cables on vertical suspenders. This type of bridge has cables suspended between towers, plus vertical suspender cables that carry the weight of the deck below, upon which traffic crosses
