MILWAUKEE (CBS 58) -- A topping off ceremony was held Thursday, marking a milestone Potawatomi Hotel and Casino. 

The final beam was put in place before the work moves inside for the $80 million project. The hotel's expansion means 119 additional rooms and suites as well as a spa and meeting space. 

The hotel's first tower opened in 2014 and has almost 400 rooms. Combined, the two towers will have 500 guest rooms and suites.
