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.
