Echelon is a casino and hotel being built on the Las Vegas Strip. Built by Boyd Gaming Corporation, it will replace for the Stardust Resort & Casino. Echelon has an estimated cost of $4 billion with construction beginning in 2007 and the opening was initially planned for in 2010. On August 1, 2008, Boyd Gaming announced that construction of Echelon would be delayed for 3 to 4 quarters due to changes in U.S. economic conditions. Amid falling profits in 2009, Boyd announced that the project will be suspended for at least three to five years.

Echelon will be a multi-use project on 87 acres (35 ha) with a 140,000 sq ft (13,000 m²) casino, 4 hotels providing 5,300 rooms, 25 restaurants and bars, the 650,000 sq ft (60,000 m²) Las Vegas Expo Center, and a 1,000,000 sq ft (93,000 m²) convention center. The Echelon Resort will be a 3,300 room hotel owned and operated by Boyd. The other hotels are expected to be a Shangri-La Hotel, a Delano Hotel, a Mondrian Hotel, and the Echelon Tower.
