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.

Spans - The Gowanus Canal, Brooklyn
According to the DOT,
"The Union Street Bridge is a double leaf Scherzer rolling lift bascule supporting Union Street over the Gowanus Canal in the borough of Brooklyn."
The Union Street Bridge is the northernmost of five bridges which cross the Gowanus Canal in Brooklyn. The other four bridges are, from north to south; 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.
The Bridge looks like a continuation of Union Street until you are right up on top of the steel grid span and can see the canal on either side.
It has two traffic lanes and two sidewalks.
Union Street is one way traveling eastbound across the span, but bicyclists ignore this constantly because Union Street runs in both directions straight from Prospect Park until 4th Avenue.
Looking North to Butler Street.
Looking South to the Carroll Street Bridge.
According to the EPA, the bridge was opened for water traffic 245 times in 1999 (the last year I could find available data.)
