Beam Bridges A beam bridge is a type of bridge that is made of horizontal beams that are supported by piers at each end. Fort Pitt Bridge Pittsburgh, PA
Cantilever Bridges Jadukata Bridge, Meghalaya Cantilever bridges are constructed with cantilevers which are horizontal beams that are only supported on one end. The majority of cantilever bridges are made using two cantilever arms that extend from opposite sides and meet in the middle.
Suspension Bridges Clifton Suspension Bridge Suspension bridges are suspended towers that are attached to from cables. The cables often hang from caissons or cofferdams. The caissons or cofferdams are implanted deep into the floor of a lake or river over which the bridge is suspended.
Truss Bridges Truss bridges are constructed using connected elements. These elements include a solid deck and a lattice of pin-jointed girders for the sides. Truss bridges are made completely of metals such as wrought iron and steel or sometimes of reinforced concrete.
Arch Bridges Arch bridges are arch-shaped and have abutments at each end. The weight of the truss bridge is thrust into the abutments at either side.

Physics of Bridges Compression is a force that acts to compress or shorten the thing it is acting on, which would be the arms of the bridge. Tension is a force that acts to expand or lengthen the thing it is acting on (bridge). Stress, or shear, is a force applied parallel to a bridge when something travels on or across it. Strain is the force which stress causes.
