Bridges Around The World

A bridge is a structure built to span a valley, road, body of water, or other physical obstacle such as a canyon, for the purpose of providing passage over the obstacle. Designs of bridges vary depending on the function of the bridge, the nature of the terrain where the bridge is constructed, the material used to make it and the funds available to build it.
Etymology
The Oxford English Dictionary traces the origin of the word bridge to an Old English word brycg, of the same meaning, derived from a hypothetical Proto-Germanic root brugjō. There are cognates in other Germanic languages (for instance Brücke in German, brug in Dutch, brú in Icelandic, brúgv in Faroese or bro in Danish, Norwegian and Swedish).
