	Bridges Hamilton Ave. Bridge

	The Hamilton Avenue Bridge is a bascule type bridge with two parallel leafs, one carrying the northbound roadway and the other carrying the southbound roadway. 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. Reconstruction Project The Department of Transportation is reconstructing the Hamilton Avenue Bridge, which was built in 1942. The new bridge will feature all-new mechanical and electrical operating systems, an improved fender system and navigation lighting for marine traffic, wider traffic lanes, and other improvements. The cost of the reconstruction is over $55 million. The reconstruction will replace the entire bridge in two stages with limited impact on motorists, pedestrians and nearby communities. There will be minimal impact on marine traffic. Contract completion is scheduled for January 2009. For a detailed description of the project, in both English and Spanish, read the brochure (in pdf format). The newly constructed northbound Hamilton Avenue Bridge opened to traffic on August 31, 2007. Northbound traffic has returned to four travel lanes toward Brooklyn Battery Tunnel. Southbound traffic has returned to three moving lanes toward Bay Ridge, 24 hours per day. One lane will remain closed for work on the bridge Control House. This work is expected to be completed before July 1, 2008, at which time the fourth southbound lane will be re-opened to traffic.
