A bridge is a structure that is used to cross a river, valley, or other obstacle.
There are more than 1/2 million bridges in the United States, and we rely on them everyday.
There are 4 main types of bridges. They are beam, arch, truss, and suspension. You can remember their names using the acronym "BATS."
Civil engineers design and build bridges. Engineers must consider many things such as the distance that the bridge must span and the types of materials available for use. Bridges must also be built strong enough to safely support their own weight as well as the weight of the objects that pass over them.
