The Gateway Center at Bronx Terminal Market, in the West Bronx, is a shopping center that encompasses less than one million square feet of retail space, built on a 17 acres (7 ha) site that formerly held the Bronx Terminal Market, a wholesale fruit and vegetable market as well as the former Bronx House of Detention, south of Yankee Stadium. The $500 million shopping center, which was completed in 2009, saw the construction of new buildings and two smaller buildings, one new and the other a renovation of an existing building that was part of the original market. The two main buildings are linked by a six-level garage for 2,600 cars. The center has earned itself a LEED "Silver" designation in its design.
