Everyone knows what bridges is, particularly for the engineer. A civil engineer can design a bridge that used to cross from point A to point B etc. Below is the history of bridges. Bridge is not a construction but it is a concept, the concept of crossing over large spans of land or huge masses of water, and to connect two far-off points, eventually reducing the distance between them. The bridge provides passage over the obstacle of small caverns, a valley, road, body of water, or other physical obstacle. Designs of bridges vary depending on the nature of the terrain and the function of the bridge and where it is constructed. The Oxford English Dictionary traces the origin of the word bridge to an Old English word brycg, of the same meaning, derived from German root brugj?.

The first bridges were believed to be made by nature ¡ª as simple as a log fallen across a stream. This is called as nature made bridge/natural bridge.
Those picture above are traditional bridges. It can be made from pans of wooden logs or bamboo.
Facts about Bridges ? Bridges can be friendly to the environment. ? Some bridges go absolutely¡­nowhere. ? Bridges provide border security. ? Traditional bridge designs can be as stable than modern ones. ? The highest bridge on earth was completed in 2016. ? Bridges can be made from glass.
General Function / Importance of Bridges A bridge is a link that connects both ends and provide continuous access for a road network. This is true when a road encounters geographical barriers such as rivers, ravines, lakes, tributaries making it impossible to pursue to its destination. Desirous of extending mobility to spur development through the flow of resources ,bridges are support structures for a road link to facilitates trade and relationships among different cultures as a result of the accessibility thru travel by land.
Types of Bridges For ease of use, Garrett¡¯s Bridges classifies six categories of bridges as follows: ? Beam Bridge ? Truss Bridge ? Arch Bridge ? Cantilever Bridge ? Suspension Bridge ? Cable Stayed Bridge
Beam bridge The most simple and common type of bridge used in the real world. This type can be quite effective, even if it isn¡¯t very beautiful. Most highway bridges fall under this category, made from Beams and reinforced concrete.
Truss bridge Truss bridges are fun because it is easy to analyze them using the Method of Joints, or by using a program such as the Bridge Designer from Jonhs Hopkins University.
Arch bridge Arch bridges are beautiful, and effective. In real life their effectiveness has a limited range, meaning they are limited in effective length. How Stuff Works does a pretty good job explaining Arch Bridges.
Cantilever bridge The Cantilever is a very interesting concept. It supports the weight with a counter weight on one end. The problem with using a Cantilever (as well as Suspension and Cable Stayed bridges) is that they need to be anchored down to something.
Suspension bridge Suspension bridges are some of the most beautiful structures known to mankind. Their elegant curved cables. Not only are they nice to look at, but they allow engineers to design longer spans than any other type (with the exception of Cable Stayed).
Cable Stayed bridge Cable Stayed bridges are similar in concept to suspension bridges, and thus are sometimes lumped together with them. However, they differ in that there is not one continuous cable that stretches from one end of the bridge to the other.
