«Brooklyn Bridge as the National Icon of the USA»
The Brooklyn Bridge is a popular landmark in the New York City. Brooklyn Bridge had existed for the longest time in the United States. It is also one of the longest bridges in the United States. The bridge has a length of 6016 foot. It extends over the East River. It is connected with the Manhattan and Brooklyn boroughs. It has a neo gothic design. It was open to be accessible by the public in 1883. It is the world s longest suspension bridge. Hailed by some as the Eighth Wonder of the World when it opened in 1883, the Brooklyn Bridge is one of the world's most recognizable and beloved icons. For over one hundred years it has excited and fascinated with stories of ingenuity and heroism, and it has been endorsed as a flawless symbol of municipal improvement and a prime emblem of American technological progress.
History of the Brooklyn Bridge
began in 1869. The Brooklyn Bridge was completed fourteen years later and was opened for use on May 24, 1883. On that first day, a total of 1,800 vehicles and 150,300 people crossed. The bridge «s main span over the East River is 1,595 feet (486 meters). The bridge cost $ 18 million to build and approximately 27 people died during its construction. A week after the opening, on May 30, a rumor that the Bridge was going to collapse caused a stampede which crushed twelve people.the time it opened, it was the longest suspension bridge in the world - fifty percent longer than any previously built -and has become a treasured landmark. Additionally, for several years the towers were the tallest structures in the United States. Since the 1980s, it has been floodlit at night to display its architectural features. The architecture style is Gothic, with characteristic pointed arches above the passageways through the stone towers.bridge was designed by an architectural firm owned by John Augustus Roebling in Trenton, New Jersey. Roebling and his firm had built smaller suspension bridges, such as the John A. Roebling Suspension Bridge in Cincinnati, Ohio and the Waco Suspension Bridge in Waco, Texas, that served as the engineering prototypes for the final design. As construction was beginning, Roebling »s foot was seriously injured in an accident; within a few weeks, he died of tetanus. His son, Washington, succeeded him, but was stricken with caisson disease (decompression sickness), due to working in compressed air with the sandhogs, and was only capable of limited speech or movement. Washington's wife, Emily Warren Roebling, trained herself in engineering so she could communicate his wishes to the builders. When the bridge opened she was also the first person to cross it. Washington Roebling was unable to leave his home and watched the construction through a telescope.the time the bridge was built, the aerodynamics of bridge building had not been worked out. Bridges were not tested in wind tunnels until the 1950s - well after the collapse of the Tacoma Narrows Bridge in the 1940s. It is therefore fortunate that the open truss structure supporting the deck is by its nature less subject to aerodynamic problems. Roebling designed a bridge and truss system that was six times as strong as he thought it needed to be. Because of this, the Brookl...
