The Greenpoint Avenue Bridge is a drawbridge that carries Greenpoint Avenue across Newtown Creek between the neighborhoods of Greenpoint, Brooklyn and Blissville, Queens in New York City. Also known as the J. J. Byrne Memorial Bridge, the bridge is named after James J. Byrne, who served as Brooklyn Borough President from September 1926 until he died in office on March 14, 1930. Previously, Byrne was the Brooklyn Commissioner of Public Works.
The Greenpoint Avenue Bridge is the sixth bridge to cross Newtown Creek in this location. In the 1850s, Neziah Bliss built the first drawbridge, which was called the Blissville Bridge. It was followed by three other bridges before being replaced by a new bridge in March 1900. A new bridge opened in 1929 and after suffering from mechanical problems it was replaced by the current structure in 1987.
On March 30, 2009, New York City Mayor Michael Bloomberg held a press conference at the Greenpoint Avenue Bridge, announcing that it would receive $6 million in federal stimulus funds, which will be used to rehabilitate the bridge.
In 2011 New York City DOT proposed an extension of the existing Greenpoint Ave bike lane on the Brooklyn side across the bridge. The local Greenpoint businesses opposed the project because of a projected loss of 50 parking spaces. As of 2013 the Greenpoint Ave bike lane awkwardly terminates at the base of the bridge.
