  1. TYPES OF BRIDGES

  2. BEAM BRIDGE 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.

  3. ARCH BRIDGE In the arch type of bridge, weight is carried outward along two paths, curving toward the ground.

  4. SUSPENSION BRIDGE 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.

  5. CANTILEVER BRIDGE 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.
