Atlanta crushed about 200,000 tons of Georgia Dome concrete after the 2017 demolition; the rubble became the base for three new projects on the same downtown site

Thousands of people lined up on the rooftops, at the parking lots and against the windows of downtown Atlanta hotels on a November morning in 2017 to watch the Georgia Dome fall. The 25-year-old home of the Falcons, two Super Bowls, an Olympics, and a Final Four, blew up at 7:30 a.m. in less than 12 seconds. The building took 30 months to build and was destroyed by a force of about 240 tons of explosives.
