A bridge is a structure built to span a gorge, valley, road, railroad track, river, body of water, or any other physical obstacle. Designs may be built higher than otherwise needed in order to allow other traffic (particularly ship traffic) beneath.
The purpose of a bridge is to allow people travelling or cargo being transported easier passage by providing a more uniform, and more easily navigable route than what would otherwise be an uneven or impossible path.
History
The first bridges were spans made of wooden logs or planks and eventually stones, using a simple support and crossbeam arrangement.
