Brooklyn Bridge’s construction started at 1870, and it was finished at 1883. This bridge is located in the city of New York, in the United States of America and crosses the East River connecting the island of Manhattan with Brooklyn. Before it was created, people had to cross the river on a ferry; this was slow, expensive and in the winter, when the water froze, the ferry was unable to navigate. Is because of all this troubles, that John August Roebling suggested the construction of a bridge that connected both sides of the river. He already had experience in suspension bridges and designed the bridge to be six times stronger than it needed to be, this allowed the construction to resist longer than any other bridge made at the time. Soon after the beginning of the works, John August Roebling suffered a paralyzing injury that stopped him from being able to visit the construction. His wife, Emily Warren Roebling studied mathematics and physics in order to be able to replace him supervising the process of the creation of the bridge. She was the first person to cross it when in was inaugurated. This bridge carries motor vehicles and has a separate walkway for pedestrians and bicycles. The Brooklyn Bridge has two towers that have the purpose of both sustaining the road high enough so it doesn’t interfere with the traffic in the water, and supporting four main cables that hold the entire structure made of thinner steel wires, this cables were made by mistake with a cheaper material than the one that had been selected but thanks to John August design it only caused the bridge to be four times stronger than it needed to be, instead of six. The two towers also define the architectural style of the bridge as neo gothic having each of them two pointed arches, characteristic of this style that also make the bridge aerodynamic. The Brooklyn Bridge is an icon of New York City, is beautiful, imposing and useful and its age and design make it a great example of architecture.
