Billie Jean King National Tennis Center

The USTA Billie Jean King National Tennis Center is a stadium complex within Flushing Meadows–Corona Park in Queens, New York City. It has been the home of the US OpenGrand Slamtennis tournament, played every year from late August to early September, since 1978 and is operated by the United States Tennis Association (USTA). The facility has 22 courts inside its 46.5 acres (0.188 km; 0.0727 sq mi) and 12 in the adjoining park. The complex's four stadiums are among the largest tennis stadiums in the world; Arthur Ashe Stadium tops the global list with a listed capacity of 23,200. When the facility was built in 1978, all 33 courts used the DecoTurf cushioned acrylic surface, as did Court 17, added in 2011. However, in 2020, the court surfaces were replaced with Laykold.
