The tribe debuted the 12-story Grand Tower four years later to accommodate casino patrons. Back then, it featured a 100,000-square-foot casino. The hotel and casino resort originally opened doors in 2006 as Choctaw Casino. News about the Durant-based property’s expansion first emerged last fall. A subsidiary of major general contractor Tutor Perini was picked to deliver the project. The Choctaw Nation of Oklahoma broke ground on Thursday on a previously announced $500 million plan for the expansion of the Choctaw Casino & Resort in Durant, Oklahoma. Choctaw Casino & Resort is expected to debut more than 1,000 new rooms and additional amenities in the spring of 2021
