A bridge is a structure to save natural obstacles such as rivers, valleys, lakes and inlets, and artificial barriers such as railways or roads in order to join our community roads, animals and goods.
The infrastructure of the bridge is formed by the stirrups or end stanchions, batteries or central supports and foundations, that form the basis of both. The superstructure consists of the board or part that directly supports loads and armor, consisting of beams, cables, or vaults and arches which transmit loads board batteries and temper.
