The Williamsburg Bridge is a suspension bridge across the East River in New York City, connecting the Lower East Side of Manhattan with the Williamsburg neighborhood of Brooklyn. Originally known as the East River Bridge, the Williamsburg Bridge was completed in 1903. At 7,308 feet (2,227 m) long, it was the longest suspension bridge span in the world until 1924. Proposed in January 1892, the bridge project was approved in 1895. Work began on June 19, 1896, under chief engineer Leffert L. Buck. Despite delays and funding shortfalls, the bridge opened on December 19, 1903. In addition to roads, walkways, and New York City Subway tracks, the bridge had four trolley tracks, which were replaced…

The Bear Mountain Bridge, ceremonially named the Purple Heart Veterans Memorial Bridge, is a toll suspension bridge in New York State. It carries US 6 and US 202 across the Hudson River between Bear Mountain State Park in Rockland and Orange County and Cortlandt in Westchester County. At completion in 1924 it was the longest suspension bridge in the world until this record was surpassed 19 months later by the Benjamin Franklin Bridge between Philadelphia and Camden, New Jersey. Like the Williamsburg Bridge in New York City, the approach spans of the Bear Mountain Bridge are unsuspended; only its main span (between the towers) is suspended by cables. The span enables connections between the…

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 t…

The Brooklyn Bridge is a cable-stayed suspension bridge in New York City, spanning the East River between the boroughs of Manhattan and Brooklyn. Opened on May 24, 1883, the Brooklyn Bridge was the first fixed crossing of the East River. It was also the longest suspension bridge in the world when opened, with a main span of 1,595.5 feet (486.3 m) and a deck 127 ft (38.7 m) above mean high water. The span was originally called the New York and Brooklyn Bridge or the East River Bridge but was officially renamed the Brooklyn Bridge in 1915. Proposals for a bridge connecting Manhattan and Brooklyn were first made in the early 19th century; these plans evolved into what is now the Brooklyn Bridg…

The world's longest suspension bridges are listed according to the length of their main span (i.e., the length of suspended roadway between the bridge's towers). The length of the main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge. If one bridge has a longer span than another, it does not necessarily mean that the bridge is longer from shore to shore (or from abutment to abutment). Suspension bridges have the longest spans of any type of bridge. Cable-stayed bridges, the next longest design, are practical for spans up to just over on…
