Suspension Bridges in New York City
The five boroughs that make up New York City are surrounded by water especially Manhattan which is an island. In order to connect the boroughs the city has built many bridges and the most impressive and famous of these bridges are all suspension bridges.
The main designer and builder of most of the suspension bridges in New York City was Othmar Ammann a structural engineer who was the bridge engineer for the Port Authority of New York. Ammann designed and built the George Washington, Triboro, Whitestone, Throgs Neck and Verrazano Narrows Bridges which are all suspension bridges and some of the most famous bridges in the world. Ammann also helped to build the Golden Gate Bridge in San Francisco.
The Brooklyn Bridge was built by engineer John A. Roebling spanning the East River connecting Manhattan with Brooklyn from 1870-1883. When finished it was the longest suspension bridge in the world and considered a triumph of man over nature with 150,000 people and 1,800 vehicles crossing the bridge the first day it was opened. The Brooklyn Bridge is 5,989 feet long with a clearance of 135 feet above the water and is still one of the most famous bridges in the world.
George Washington Bridge
The George Washington Bridge or GWB is a 4,760 foot long suspension bridge over the Hudson River connecting upper Manhattan with Fort Lee, New Jersey. The bridge has an upper and a lower level with a total of 14 lanes of traffic and is the world's busiest motor vehicle bridge with over 106 million vehicles traveling over the George Washington Bridge each year. The GWB was designed by engineer Othmar Ammann, built from 1927 to 1931 and is 212 feet above the Hudson River and offers travelers over the bridge great views of the Hudson, the Palisades and New York City.
The Manhattan Bridge is a 6,855 foot long suspension bridge over the East River connecting Lower Manhattan with Brooklyn. Built in 1909 the Manhattan Bridge is 135 feet above the water and was designed by the infamous suspension bridge engineer Leon Moisseiff whose Tacoma Narrows Bridge in Washington collapsed in a windstorm four months after it opened in 1940.
