Osage Sky News 6HD flew overhead as the new Tulsa Osage Casino marked a milestone on Monday.
Construction crews added the final beam at the tallest point of the new hotel, near 36th street North and Osage Drive.
The $150-million expansion includes a 114-room hotel and a completely re-designed casino.
"The casino will have over 1,500 electronic games, 16 table games. We'll have a poker room, as well as a full cafe, a sports bar, a full brewery and a brew pub," said Osage Casino CEO Byron Bighorse.
The 18-month project is expected to be finished by mid-2018.
The Osage Nation says it will bring more jobs to Tulsa, and more revenue for services offered by the tribe.
