The Barclays Center, Brooklyn (under construction)

The Barclays Center is a sports arena currently under construction in Brooklyn, New York City. The arena is being built partly on a platform over the Metropolitan Transportation Authority-owned Vanderbilt Yards at Atlantic Avenue. It is part of a proposed $4.9 billion sports arena, business and residential complex. The arena is intended to serve as a new home for the National Basketball Association's New Jersey Nets, currently based at Prudential Center in Newark, New Jersey. The team will be renamed the Brooklyn Nets starting with the arena's expected opening season of 2012–13.

The project is being developed by developer Forest City Ratner, who acquired the Nets in 2004, with the purpose of moving them from New Jersey to this site near the Atlantic Avenue – Pacific Street subway station and the Long Island Rail Road's Atlantic Terminal in Brooklyn, one of the most transit-accessible locations in the city. The move would mark the return of major league sports to Brooklyn, which has been absent since the departure of the Dodgers to Los Angeles in 1957.
