Part two of the Riviera parking garage was demolished on Thursday morning.
The demolition was caught on camera by a man who was at Turnberry Place. He posted the video to Instagram.
It was initially reported as an implosion. A spokesperson for the Las Vegas Convention and Visitors Authority says that it was a "traditional demolition" though and no explosives were used.
Clauss Contruction says today's demolition was a controlled collapse, and even though it looked like an implosion, it wasn't.
Crews used excavators to hammer into columns, that are all connected by cables. Once enough pressure is applied, gravity does the rest.
Part one of the parking garage demolition took place in late April.
The historic Riviera was closed after the LVCVA purchased the property in 2015 for $191 million in order to build a new convention center.
It was announced in April that the Riviera would be imploded in two separate implosions this summer. The demolitions are scheduled for June and August.
A petition was also filed in April though to stop the demolition. The group behind the petition wants the Riviera to be preserved for historical reasons.
