  Beam bridge-typically span up to 250 feet, and they're also the cheapest and easiest bridges to build. It is supported by abutment at each end of the deck. There are no moments transferred through the support. structural.

  Drawbridge- It is a movable bridge similar to those that spanned medieval castle moats. Draw bridges are made primarily from concrete and steel. It may open at one end and lift to one side (single leaf) or open in the middle and lift to both sides (double leaf).

  Suspension bridge - a type of bridge in which the deck is hung below suspension cables on vertical suspenders. Suspension bridges are originally made from rope and wood.But now, Modern suspension bridges use a box section roadway supported by high tensile strength cables.

  Truss bridge-consists of an assembly of triangles. Truss bridges are commonly made from a series of straight, steel bars.

  Arch Bridge-Arch bridges have abutments at each end. It uses a curved design that does not need supporting piers in its center, eliminating obstacles for river traffic. Today, most arch bridges are made of steel or concrete. Thousand years ago, Romans built arches out of stone.

  Side spar cable stayed bridge:-
  
  
  
  
  
  
  
  A side-spar cable-stayed bridge may be an otherwise conventional cable-stayed bridge but its cable support does not span the roadway, rather being cantilevered from one side. The bridge illustrated is located in Winnipeg, Manitoba, Canada. The side-spar principle is not limited to a straight bridge, however. The tower could be offset and the bridge deck wrap around the spar in an arc. This subtype should not be confused with a single tower cable-stayed bridge, which may be asymmetrical in form and possesses only a single tower on one side of the gap to be crossed, nor with the cantilever spar cable-stayed bridge, which has span supporting cables on only one side of the tower along the direction of the roadbed.

  Cantilever bridge- is a bridge that is rigidly supported at one end. This bridge is a variation of the simple beam bridge. It is formed by two projecting beams or trusses that are joined in the center by a connecting member and are supported on piers and anchored by counterbalancing members. It consists of three parts: the outer beams, the cantilevers, and the central beam.

  Truss bridges
  These are the most economic bridges as they provide maximum place for movement of vehicles. The load transfer mechanism is important consideration while designing.
