United States tennis officials will spend more than half a billion US dollars to install moveable Wimbledon-style translucent roofs on two stadiums to bring the US Open up to standard.
The project is set to include a huge roof over the Arthur Ashe showcase stadium in Flushings, New York, plus a second arena with the possibility of being covered in case of rain.
US federation president Dave Haggerty says the roof over the massive showcase court should be operational by 2018.
Bad weather has forced the men's final to be played on a Monday at the last five editions.
With the New York announcement, only the French Open currently lacks a showcourt roof, with plans to build one over the Chatrier stadium currently held up in legal disputes.
The Australian Open is working on its third roof, and Wimbledon covered Centre Court in 2009.
