Las Vegas-based Ameristar Casinos unveiled details today of its plan to develop a $910 million “casino resort spa” in Springfield, Mass., one of three casino projects proposed for the city.

According to a press release, Ameristar would develop a 150,000-square-foot facility minutes from downtown on a 40-acre construction-ready site at the junction of Interstate 291 and Page Boulevard. The casino would feature 3,300 slot machines and 110 table games, including a poker room.

Ameristar Springfield also would include a 500-room luxury hotel with 50 suites, indoor and outdoor swimming pools, a spa, a fitness center and retail amenities. The plan also calls for diverse food and beverage options and a conference and entertainment center, along with garage parking for 4,300 vehicles.

The resort is designed to accommodate significant future expansions of the casino, hotel and parking garages.

Ameristar said its casino would include world-renowned, nationally recognized restaurateurs and locally owned favorites. Celebrity chefs Wolfgang Puck and Martin Yan would oversee restaurants, and former Red Sox second baseman and current New England Sports Network color analyst Jerry Remy would feature his Jerry Remy’s Sports Bar & Grill.

MGM Resorts International and Penn National Gaming also have proposed Springfield casinos, joining a competitive western Massachusetts field that includes the Mohegan Tribal Gaming Authority, which operates Mohegan Sun in Uncasville. The authority has proposed a casino for Palmer, a town east of Springfield.

The Massachusetts Gaming Commission is expected to issue one casino license for western Massachusetts.
