The United States Tennis Association have released details of their proposed development of Flushing Meadows, home to the US Open, but they do not include a roof.
The major changes will see the construction of a new 15,000 Louis Armstrong Stadium - on the site of the existing 10,000 capacity one - as well as a brand new Grandstand Stadium on currently unused land at the Billie Jean King National Tennis Center. This will house 8,000 fans, replacing the current 6,000-capacity court which, like Armstrong, was built in the 1960s.
However, there are no plans to build a roof over the Arthur Ashe Stadium or the new Armstrong facility - something which will surprise many.
The US Open has overrun in each of the last four years due to the weather and come 2017 - when the French Open add a retractable roof to their main court - the tournament will be the only Grand Slam event without the ability to play in all conditions.
In addition, seven tournament courts on the southern section of the site will be relocated between 30-50 feet, and a new walkway will be built to allow for easy access through the southern part of the site.
On the north-west section, five practice and two tournament courts will be replaced and linked by a new, elevated viewing platform that will provide better seating and viewing options for fans.
The project will enable the facility to accommodate an extra 10,000 people each day during the US Open, increasing attendance by approximately 100,000 new visitors.
Jon Vegosen, chairman of the board and president of the USTA, said: "Our goal remains to ensure that the USTA Billie Jean King National Tennis Center remains a world-class facility for the top professional tennis players, for the hundreds of thousands of fans who annually attend the US Open, and, as importantly, the near hundred thousand recreational tennis players who use this facility all year round.
"The strategic vision will enable us to achieve this goal."
New York City mayor Michael Bloomberg added: "The US Open is one of the city's greatest sporting events, and it generates more than $750 million a year in economic activity.
"The city recognises the crucial need to improve the USTA facility and supports this vision so that the center remains a top-ranked tennis venue capable of hosting the US Open and thereby allowing the tournament to remain in New York City for many decades."
The USTA expect the development to take place throughout a "multi-year period" and cost "hundreds of millions of dollars".
