MGM Resorts is scheduled to break ground on its $800 million casino in Springfield, Massachusetts on Tuesday.

The resort casino will occupy a 14.5 acre site in Springfield’s South End, which was destroyed by a tornado almost four years ago.

The casino is expected to open in 2017.

The Massachusetts Gaming Commission granted MGM an integrated resort license for the state’s western part. Later on, it awarded Wynn Resorts a license for the Boston area but that project has not yet begun construction in Everett.
