The Brooklyn Bridge is a bridge in New York City and is one of the oldest suspension bridges in the United States. Completed in 1883, it connects the boroughs of Manhattan and Brooklyn by spanning the East River. It has a main span of 1,595.5 feet (486.3 m), and was the first steel-wire suspension bridge constructed.
Originally referred to as the New York and Brooklyn Bridge and as the East River Bridge, it was dubbed the Brooklyn Bridge, a name from an earlier January 25, 1867, letter to the editor of the Brooklyn Daily Eagle, and formally so named by the city government in 1915. Since its opening, it has become an icon of New York City, and was designated a National Historic Landmark in 1964 and a National Historic Civil Engineering Landmark in 1972.
New York is the most populous city in the United States and the center of one of the most populous urban agglomerations in the world—the New York metropolitan area. The city is referred to as New York City or the City of New York to distinguish it from the State of New York, of which it is a part. A global power city, New York exerts a significant impact upon commerce, finance, media, art, fashion, research, technology, education, and entertainment. The home of the United Nations Headquarters, New York is an important center for international diplomacy and has been described as the cultural and financial capital of the world.
On one of the world's largest natural harbors, New York City consists of five boroughs, each of which is a county of New York State. The five boroughs—the Bronx, Brooklyn, Manhattan, Queens, and Staten Island—were consolidated into a single city in 1898. With a census-estimated 2013 population of 8,405,837 distributed over a land area of just 305 square miles (790 km2), New York is the most densely populated major city in the United States. As many as 800 languages are spoken in New York, making it the most linguistically diverse city in the world. By 2013 census estimates, the New York Metropolitan Area's population remains by a significant margin the United States' largest Metropolitan Statistical Area, with approximately 19.9 million people, and is also part of the most populous Combined Statistical Area in the United States, containing an estimated 23.4 million people. New York's 2012 gross metropolitan product of over US$1.3 trillion ranked behind the GDP of only twelve nations.
