The Riviera Hotel and Casino, a classic that spent 60 years on the Las Vegas Strip, closed yesterday, the Associated Press reported. The Las Vegas Convention and Visitors Authority bought the 2,075-room building and 26 acres it sits on in February for $182.5 million plus $8.5 million in related transaction costs. Furniture and fixtures inside the casino-hotel are expected to be auctioned by NCL, National Content Liquidators, starting May 14 until everything is sold. The publicly-funded tourism agency plans to tear it down and expand the Las Vegas Convention Center to the Strip. The goal is to bring it down before the end of the year, said Heidi Hayes, a spokeswoman for the agency.
