A bridge is a structure built to span physical obstacles without closing the way underneath such as a body of water, valley, or road, for the purpose of providing passage over the obstacle.

There are many different designs that each serves a particular purpose and apply to different situations. Designs vary depending on the function the nature of the terrain where is constructed and anchored, the material used to make it, and the funds available to build it.

The first is made by humans were probably spans of cut wooden logs or planks and eventually stones, using a simple support and crossbeam arrangement. Some early Americans used trees or bamboo poles to cross small caverns or wells to get from one place to another.

A common form of lashing sticks, logs, and deciduous branches together involved the use of long reeds or other harvested fibers woven together to form a huge rope capable of binding and holding together the materials used in early bridges.

Bridge can be categorized in several different ways. Common categories include the type of structural elements used, by what they carry, whether they are fixed or movable, and by the materials used.

The most bridge is a fixed bridge, meaning they have no moving parts and stay in one place until they fail or are demolished. Temporary bridges, such as Bailey bridge, are designed to be assembled, and taken apart, transported to a different site, and re-used.

They are important in military engineering and are also used to carry traffic while an old bridge is being rebuilt. A movable bridge is designed to move out of the way of boats or other kinds of traffic, which would otherwise be too tall to fit. These are generally electrically powered.
