What is a Bridge?
One of the outstanding statesmen once said in his speech. “There can be little doubt that in many ways the story of bridge-building is the story of civilization. By it we can readily measure an important part of a people’s progress.” Great rivers are important means of communication for in many parts of the world they have been, and still are. the chief roads. But they are also barriers to communication and people have always been concerned with finding ways to cross them.

For hundreds of years men have built bridges. A bridge is a structure used by people and vehicles to cross areas that are obstacles to travel. Engineers build bridges over lakes, rivers, canyons, and busy highways and railroad tracks. Without bridges, people would need boats to cross waterways and would have to travel around such obstacles as canyons and ravines.

Bridges range in length from a few feet or meters to several miles or kilometers. A bridge must be strong enough to support its own weight as well as the weight of the people and vehicles that use it. It also must resist natural occurrences, including earthquakes, strong winds. and changes in temperature. Most modem bridges have a concrete, steel, or wood framework and an asphalt or concrete roadway. The roadway is the part of a bridge on which people and vehicles travel.
