The Hamilton Avenue Bridge

Only 2,013 more to go ...


The Hamilton Avenue Bridge in Brooklyn is one of five bridges which span the Gowanus Canal.

The five bridges are, in order from North to South, The Union Street Bridge, The Carroll Street Bridge, The Third Street Bridge, The Ninth Street Bridge, and the Hamilton Avenue Drawbridge which runs parallel to the Gowanus Expressway at the mouth of the canal.

Most of the length of Hamilton Avenue runs below the elevated portion of the Gowanus Expressway, including the bridge. The bridge connects Smith Street and Second Avenue over the Gowanus Canal and is the first canal crossing north of the Gowanus Bay.


"The bridge is comprised of two bridges, each consisting of one bascule span with each span carrying four lanes of one-way traffic (one northbound and one southbound) and a pedestrian sidewalk. Hardesty & Hanover LLP (as Waddell & Hardesty) designed the existing bridges based on the patented Hanover skew design—an innovative approach to skewed bascule crossings. The Hamilton Avenue Bridge is one of the two remaining structures of this type."

The Bridge is currently undergoing reconstruction.
The reconstruction will replace the entire bridge in two stages. Completion is scheduled for January 2009.

On June 28, 2008 at 12:01 am the entire southbound bridge will be taken out of service. The current 4-lane northbound bridge will be converted to 2 lanes northbound and 2 lanes southbound to facilitate the replacement of the southbound bridge.


The Hamilton Avenue Bridge has a vertical clearance of 19 feet at
mean high water, and 23 feet at mean low water in the closed position.
The existing drawbridge operating regulations require the bridge to open on signal at all times.

"Originally christened Blackwell’s Island Bridge, and intended to link Manhattan’s Harlem Line with the Long Island Railroad, the colossal, two-decked Queensboro Bridge is one of the greatest cantilever bridges in the history of American bridge design.
A collaboration between the famed bridge engineer Gustav Lindenthal (1850-1935) and architect Henry Hornbostel, the Queensboro’s massive, silver-painted trusses span the East River between 59th Street in Manhattan and Long Island City in Queens and offer spectacular views of midtown Manhattan, highlighted by the Empire State Building, the Chrysler Building, and the United Nations. Often referred to as the 59th Street Bridge, the Queensboro’s completion preceded that of the Manhattan Bridge by nine months."

The Beaux-Arts style bridge was given landmark status in 1974, one of only ten such designations in NYC.

The bridge has been immortalized by numerous artists and musicians, including Simon & Garfunkel in their hit song, "The 59th Street Bridge Song/Feelin’ Groovy."
It has also served as a famous backdrop, denoting the wealth and luxury of an East Side, Sutton Place address in movies such as "The Tender Trap" where it is prominently visible through the windows of Frank Sinatra's bachelor pad.
More recently, the Green Goblin forced a showdown with Spiderman at the bridge by dangling ladylove, MaryJane from one of the supports while simultaneously threatening the passengers of the Roosevelt Island tramway.


Pedestrian and Bicycle access to the Queensboro Bridge -
"The North Outer Roadway is open for the exclusive use of bicyclists and pedestrians 24 hours a day, seven days a week. The path connects Long Island City with Midtown Manhattan. T.A. worked for nearly twenty years to see this permanent route established. Nicknamed "The People's Roadway," the path's temporary closures in the 1980s and 1990s became a potent symbol of government indifference to bicyclists and walkers. Today, the path is a heavily used bike commuter route, though the existing Manhattan approach forces cyclists exiting to the south to make a dangerous three-block detour in order to reach Second Avenue." -

Manhattan entrance: 60th Street, between Second and First Avenues
Queens entrance: Queens Plaza and Crescent Street

Other bridge factoids -
You can walk out of the front door of Scores on the Manhattan side, straight onto the pedestrian walkway, across to LIC, Queens and into Scandals - if a walking tour of NYC strip clubs is your idea of fun.
Until 1970, an industrial sized elevator connected Roosevelt Island with the bridge. It was big enough to carry vehicles and a proposal is now on the table to revisit the idea. Due to increased security in post - 9/11 NYC, water traffic is often re-routed away from the United Nations to the East Channel of the river. The passing ships require that the Roosevelt Island drawbridge be raised, cutting the island off to vehicles.
In an article published Feb, 4 1909, the New York Times reported that 235 people had applied for permission to be the first to jump off the soon to be completed bridge. Some were professional divers, other parachutists, a few were just desperate, but in the end they were all denied.
"The Celebration Committee announces that no bridge jumping will be allowed."
