NYC-Manhattan_Bridge

New York is the most populous city in the United States and the center of the New York Metropolitan Area, one of the most populous metropolitan areas in the world. New York exerts a significant impact upon global 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 capital of the world. The city is also 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.

Located on one of the world's largest natural harbors, New York City consists of five boroughs, each of which comprises a state county. The five boroughs — The Bronx, Brooklyn, Manhattan, Queens, and Staten Island — were consolidated into a single city in 1898. With a 2010 United States Census population of 8,175,133 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. The New York City Metropolitan Area's population is the United States' largest, with 18.9 million people distributed over 6,720 square miles (17,400 km²), and is also part of the most populous combined statistical area in the United States, containing 22.1 million people as of the 2010 Census.

The United States of America (commonly abbreviated to the United States, the U.S., the USA, America, and the States) is a federal constitutional republic comprising fifty states and a federal district. The country is situated mostly in central North America, where its forty-eight contiguous states and Washington, D.C., the capital district, lie between the Pacific and Atlantic Oceans, bordered by Canada to the north and Mexico to the south. The state of Alaska is in the northwest of the continent, with Canada to the east and Russia to the west, across the Bering Strait. The state of Hawaii is an archipelago in the mid-Pacific. The country also possesses several territories in the Pacific and Caribbean.

At 3.79 million square miles (9.83 million km²) and with over 312 million people, the United States is the third or fourth largest country by total area, and the third largest by both land area and population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The U.S. economy is the world's largest national economy, with an estimated 2011 GDP of $15.1 trillion (22% of nominal global GDP and over 19% of global GDP at purchasing-power parity). Per capita income is the world's seventh-highest.

The Manhattan Bridge is a suspension bridge that crosses the East River in New York City, connecting Lower Manhattan (at Canal Street) with Brooklyn (at Flatbush Avenue Extension). It was the last of the three suspension bridges built across the lower East River, following the Brooklyn and the Williamsburg bridges. The bridge was opened to traffic on December 31, 1909 and was designed by Leon Moisseiff, who later designed the infamous original Tacoma Narrows Bridge that opened and collapsed in 1940. It has four vehicle lanes on the upper level (split between two roadways). The lower level has three lanes, four subway tracks, a walkway and a bikeway. The upper level, originally used for streetcars, has two lanes in each direction, and the lower level is one-way and has three lanes in peak direction. It once carried New York State Route 27 and later was planned to carry Interstate 478. No tolls are charged for motor vehicles to use the Manhattan Bridge.

The original pedestrian walkway on the south side of the bridge was reopened after forty years in June 2001. It was also used by bicycles until late summer 2004, when a dedicated bicycle path was opened on the north side of the bridge, again in 2007 while the bike lane was used for truck access during repairs to the lower motor roadway, and for a third time in 2011, when ongoing construction on the north side of the bridge necessitated narrow shelters, narrowing the path to make it unsafe for cycling.
