LAS VEGAS – The aging Riviera Hotel and Casino on the Las Vegas Strip will age no more as of noon.

The 60-year-old casino-hotel is expected to close its doors at that hour Monday.

The 2,075-room building and the 26 acres it sits on was sold to the Las Vegas Convention and Visitors Authority in February.

The publicly-funded tourism agency plans to tear down the casino-hotel where Liberace and Frank Sinatra were once headliners and expand the Las Vegas Convention Center to the Strip.

“The Riv” is among the few remaining hotel-casinos that got its start in Sin City’s early mob-led days.

The property has struggled in recent years as development around it went dormant, deterring walk-in traffic.

Furniture and fixtures inside the casino-hotel are expected to be auctioned in mid-May.
