Iron molecules on the surface of the metal mix with oxygen molecules in the air creating Iron Oxide. This is better known as rust, the process continues until all the iron is consumed and converted into rust.
The use of paint prevents the oxygen getting to the metal and causing this chemical process. if we didn't protect ths metal this way the bridge would soon become dangerously weak as the rust rotted the metal away.
