The Beam Bridge HowStuffWorks

Bridge building doesn t get any simpler than this. In order to build a beam bridge (also known as a girder bridge) all you need is a rigid horizontal structure (a beam) and two supports one at each end to rest it on.These components directly support the downward weight of the bridge and any traffic traveling over it.
