Type of Bridge

There are 4 major Types of Bridges

1.Type Beam

 
Beam - The beam type is the simplest type of bridge. The beam bridge could be anything as simple as a plank of wood to a complex structure. It is made of two or more supports which hold up a beam.

 2.Type Arch

Arch - In the arch type of bridge, weight is carried outward along two paths, curving toward the ground. 
3.Type Cantilever 
Cantilever - In the cantilever type of bridge, two beams support another beam, which is where the deck or trafficway is. The two beams must be anchored, and this must be done well.

4.Suspension/Cable Strayed

Suspension/Cable-stayed -The deck (trafficway) of a suspension bridge is hung by cables which hang from towers. The cables transfer the weight to the towers, which transfer the weight to the ground.
Cable-stayed bridges have towers, but cables from the towers go directly to the road deck, instead of spanning from tower to tower.
