AN ARTIST’S RENDITION of the planned $30 million expansion of the Island Resort and Casino in Harris.

HARRIS — The Hannahville Indian Community Tribal Council has approved a $30 million expansion of the Island Resort and Casino to add more 100 hotel rooms and a pool with “water park features.”

The addition will be connected to the south end of the current 11-story Palm Tower, complete with three guest elevators and a lobby.

A high-end dining venue, as well as convention space, are planned for the top floor.

Wisconsin firm Quintus 3D will lead the architectural and engineering aspects of the project. The firm designed the Drift Spa, new hotel lobby and retail space at the Island Resort and Casino and also works with many Indian tribes across the country. Iron Mountain firm Gundlach Champion was chosen to oversee the construction management of the project. Gundlach Champion built the Island hotel’s Sun Tower and 1998 expansion of the casino, along with the water plant and numerous other Hannahville Indian Community projects.

Engineering, design and bidding will be ongoing through spring of this year. Construction is scheduled to begin in June, with expected completion in 2021.

The resort now has more than 300 guest rooms, including suites, and a 42-site RV park. The 408,520-square-foot casino offers slots, a poker room, craps, blackjack, Spanish 21, three-card poker, let-it-ride, roulette and bingo.

The resort also includes the Drift Spa, with access to the resort’s saltwater pool, steam rooms and sauna. Dining options include the 5 Bridges Steak and Seafood House, 5 Bridges Pub, Firekeeper’s Restaurant, T.McC’s Sports Bar, Coral Reef Grille, Signature Subs & Pizza, The Coffee & Bakery Shop, as well as The Custard Shop. The Island has entertainment in its 1,315-seat showroom, as well as weekly bands and comedy entertainers in Club 41.

The resort also features Sweetgrass and Sage Run golf courses.
