WATCH: Georgia Dome implodes

ATLANTA, GA (WVUE) - One of the nation's largest domes imploded Monday morning.

The Georgia Dome was flattened in about 15 seconds at 6:30 a.m.

The Georgia World Congress Center Authority said the implosion took 12 seconds for all the explosives to go off, plus another three for grandstands to be on the ground.

The dome, which was opened in 1992, was not only the former home of the Atlanta Falcons, but also the site of two super bowls, the 1996 Olympics and NCAA tournaments.

The dome will be replaced by the $1.6 billion Mercedes-Benz stadium next door.
