This undated artist's rendering provided by the U.S. Tennis Association and architectural firm Rossetti shows the USTA Billie Jean King National Tennis Center, including a retractable roof for Arthur Ashe Stadium. The USTA says a retractable roof will be constructed over Arthur Ashe Stadium, the main venue for the U.S. Open. The Ashe roof is part of a larger plan to rebuild and expand other courts at the Billie Jean King National Tennis Center. No. 2 stadium Louis Armstrong will eventually be covered, too.
