Iron and steel bridges have been in use since the 18th century when they revolutionized the way bridges or other structures were built which enabled engineers to design and construct larger structures and buildings. Some of the oldest structures built using wrought iron and steel are still in use today. It was in 1779 that the first wrought iron bridge was built in Telford and steel replaced wrought iron as the preferred material in the 1800s and by the beginning of the 20th century, steel makers had invented carbon steel which thoroughly replaced wrought iron because of its larger reliability. Brooklyn Bridge in New York, U.S.A was the first ever steel wire steel bridge to be built in the world and serves as a historic structure today standing strong even after a century.
