A bridge is a
structure built to span physical obstacles such as a body of water, valley, or road,
for the purpose of providing passage over the obstacle. There are many
different designs that all serve unique purposes and apply to different
situations. Designs of bridges vary depending on the function of the bridge,
the nature of the terrain where the bridge is constructed and anchored, the
material used to make it, and the funds available to build it. Source
