MGM Mirage unveils $5 billion CityCenter on Strip

In a city known for being big on building big, MGM Mirage is giving the public its first look at the biggest thing ever built here -- or maybe anywhere.

To be constructed on 66 acres between the company's Bellagio and Monte Carlo casinos, the project will be anchored by a 4,000-room, 60-story hotel tower with a "sophisticated, contemporary design [that] will be demonstrably different from any building that has preceded it," the company. Also on site will be two 400-room high-end boutique-style hotels, 1,640 condominium units and 500,000 square feet of retail, restaurant and entertainment space.

"This is the most expensive privately funded project in U.S. history," said MGM Mirage CEO Terry Lanni. "You could take Rockefeller Center and throw in SoHo and Times Square, and this is bigger."
