The Manhattan Bridge is a suspension bridge that crosses the East River in New York City, connecting Lower Manhattan at Canal Street with Downtown Brooklyn at the Flatbush Avenue Extension. Designed by Leon Moisseiff, the bridge has a total length of 6,855 ft (2,089 m). The bridge is one of four vehicular bridges directly connecting Manhattan Island and Long Island; the nearby Brooklyn Bridge is just slightly farther west, while the Queensboro and Williamsburg bridges are to the north.
The bridge was proposed in 1898 and was originally called "Bridge No. 3" before being renamed the Manhattan Bridge in 1902. Foundations for the bridge's suspension towers were completed in 1904, followed by the anchorages in 1907 and the towers in 1908. The Manhattan Bridge opened to traffic on December 31, 1909, and began carrying streetcars in 1912 and New York City Subway trains in 1915. The eastern upper-deck roadway was installed in 1922. After streetcars stopped running in 1929, the western upper roadway was finished two years later. The uneven weight of subway trains crossing the Manhattan Bridge caused it to tilt to one side, necessitating an extensive reconstruction between 1982 and 2004.
