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 serve a particular purpose 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.
The Oxford English Dictionary traces the origin of the word bridge to an Old English word brycg, of the same meaning. The word can be traced directly back to Proto-Indo-European *bʰrēw-. The word for the card game of the same name has a different origin.
The first bridges 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 connective rope capable of binding and holding together the materials used in early bridges.
A bridge needs to be built, so time to bust out the cranes, right? Not so fast, a Chinese company has built a machine that has a creative way of setting girders into place. The SLJ900/32, made by the Beijing Wowjoint Machinery Company, is a 580 ton, 300 foot long and 24 foot wide mega machine that looks more like a train than a crane and acts a lot like a Stretch Armstrong action figure. Instead of using a stationary or crawler crane to lift the girder of a bridge from the ground and drop it into its place, the SLJ900/32 drives the girder onto the previously placed girder, slowly extends its arms to the next support platform, pushes the girder towards the front of the machine and then lowers it into place.

Terrifying: Eshima Ohashi Bridge in Japan looks more like a rollercoaster than a bridge This terrifying 'rollercoaster bridge' forces drivers to navigate down a steep decent so ships can pass underneath. Facts about the Eshima Ohashi: ★ 1,446 meters long ★ 250 meters of continupus concrete in the center (the third longest Ramen bridge in the world!) ★ 6.1% grade slope on the Shimane Prefecture side ★ 5.1% grade on the Tottori side ★ The bridge needed to be high in the center to allow large shops to pass under. ☆ From the Shimane side, you can get the optical illusion view at the end of the street by the sea. ☆ If you have a good telephoto lens, go even further to the other side of the sea for a better shot.

The record breaking bridge is 430 metres (1,400 ft) long and hangs 300 metres (1,000 ft) above the earth, suspended between two mountain cliffs in Zhangjiajie park. The bridge is designed by Israeli architect Haim Dotan with visitors crossing 99 panels of clear glass to reach the opposite cliff. Eight hundred people can fit on the bridge at one time with only 8,000 allowed to cross the bridge each day. The park in China’s central Hunan province is a popular tourist destination and authorities in Zhangjiajie also plan to offer bungee jumping for the bravest visitors.
