It's time to bring down the old South Shore Hospital tower in Miami Beach.
The structure that's left standing will be imploded this morning to make way for a new residential tower and park.
Police have blocked the area around 600 Alton Road .
If all goes as planned, you'll hear a horn blast three times at 9:59 and then the implosion will take place at 10.
After a site inspection, the demolition team will sound a horn five times to signal the "all clear."
