Knowra Manhattan Bridge Manhattan Bridge The Manhattan Bridge is a suspension bridge connecting Lower Manhattan and Downtown Brooklyn across the East River. Opened in 1909, it carries road traffic, subway trains, pedestrians, and cyclists.
Suspension bridge : A bridge whose deck hangs from vertical suspenders attached to main cables draped over towers and anchored at both ends. The Manhattan Bridge uses this structural form, with stiffening trusses supporting its deck.
New York and Brooklyn Bridge : The 1883 suspension bridge, now called the Brooklyn Bridge, connecting Lower Manhattan and Brooklyn across the East River. Its success helped establish the need for another crossing farther north.
Manhattan Bridge subway service : New York City Subway service carried over the Manhattan Bridge between Manhattan and Brooklyn. Multiple subway routes use its tracks, making the bridge a key link in the city’s transit network.
Manhattan Bridge approach : The roadway and viaduct structures linking the Manhattan Bridge to surrounding streets at either end. The approaches occupy substantial urban space and channel traffic into dense neighborhoods.
Leon Moisseiff : An American civil engineer known for designing suspension bridges, including the Manhattan Bridge. Moisseiff developed the bridge’s design and applied deflection theory to its long, flexible structure.
Manhattan Bridge construction : The construction project that built the Manhattan Bridge between 1901 and its opening in 1909. Construction reveals how design revisions, municipal oversight, and difficult foundations shaped the bridge.
Manhattan Bridge bicycle path : The bicycle path on the north side of the Manhattan Bridge’s upper deck. It provides a nonmotorized East River crossing alongside the bridge’s road and rail routes.
Manhattan Bridge reconstruction : The major rehabilitation work undertaken to repair and modernize the Manhattan Bridge, especially during the late twentieth century. Long-term repairs exposed the difficulty of maintaining a bridge carrying trains, cars, pedestrians, and cyclists.
Deflection theory : A bridge-design method that accounts for how a suspension bridge’s cables and deck deform under load. Moisseiff used this approach to make the Manhattan Bridge lighter than earlier designs.
New York City Department of Bridges : The municipal agency responsible for designing and building New York City bridges in the early twentieth century. The department managed the project and employed the engineers who developed its design.
