WATCH: Atlanta's Georgia Dome implodes
Atlanta's new $1.6 billion stadium — home to the NFL's Falcons and the city's hugely popular pro soccer team — has successfully risen, despite a series of construction delays over its complex retractable roof.
Now, the dome next door that Mercedes-Benz Stadium was built to replace has been brought down with explosives.
The Georgia Dome, with its history of hosting major sporting events and concerts since its 1992 debut, was imploded Monday morning.
Nearly 5,000 pounds of explosives were on hand to blast the Georgia Dome in Atlanta to smithereens Monday at 7:30 a.m. People gathered at windows of tall office buildings, at a nearby revolving hotel-top restaurant, in parking lots and at other areas around the scene downtown to watch the blast.
The dome opened in 1992, and it was flattened within about 15 seconds. The Georgia World Congress Center Authority, which includes the 71,250-seat dome, had said it would take 12 seconds for the explosives to go off plus another 3 seconds for sections of grandstands to be on the ground.
In addition to the retractable roof that opens like a camera lens, Mercedes-Benz Stadium boasts a 1,100-foot "halo board" video display and a giant steel sculpture of a falcon with its 70-foot wingspan at one of the main entrances.
The idea for the Georgia Dome dates to the mid-1980s, when civic leaders recommended a domed football stadium adjoining the city's largest convention center, the Georgia World Congress Center.
Rankin M. Smith Sr., who owned the Falcons at the time, discussed having the team play in the dome but also various other options such as building an open-air stadium in Atlanta's northeastern suburbs 30 miles from downtown and even moving the franchise to Jacksonville, Florida.
In the fall of 1987, a brochure envisioned the future "Georgia Dome" as the new home of the Falcons and a possible site for the Super Bowl, NCAA basketball tournament, Peach Bowl, high school football playoffs and even tractor pulls.
The dome hosted those, and many more.
It was the site of high school football state championships, Peach Bowls, SEC championship games, two Super Bowls, 1996 Olympic basketball, three Final Four NCAA basketball tournaments, concerts, pro wrestling and other events.
Now, Mercedes-Benz Stadium will host this season's College Football Playoff championship game, the Super Bowl in 2019 and the Final Four in 2020.
It can hold about 71,000 fans for Falcons games, and it already set records for selling more than 70,000 tickets for a couple of Atlanta United home soccer games.
The stadium was originally set to open in March, but that was pushed back multiple times as engineers struggled to finish the roof.
The stadium finally opened Aug. 26 with a Falcons' pre-season game against the Arizona Cardinals.
