The International Tennis Hall of Fame & Museum in Rhode Island, US, is set to invest US$15.7m (£9.3m, €11.4m) in the first phase of an expansion project to upgrade its visitor and playing facilities.

The museum will gain new technology and exhibitions as part of the upgrade, while additional tennis courts will be installed and facility-wide improvements will be made, including the tennis stadium.

The Hall of Fame hosts several tournaments, including the Hall of Fame Tennis Championships. Part of the ATP World Tour, the tournament is the only grass court event in North America.

The plans also look to revitalise the streetscape on nearby Memorial Boulevard, while a new building to house locker rooms, a fitness area, retail space and Hall of Fame offices is also in the works.

The 4,000-seat tennis stadium, Newport Casino, is a designated National Historic Landmark, while the facility also houses a number of shops, restaurants, offices and a theatre.

Further development is planned on the historic facility dating back to 1879, but those proposals have not yet been revealed.
