An elevated walkway under construction at Atlanta’s Botanical Garden collapsed today, killing a worker and injuring 18, the Journal-Constitution reports. Workers were pouring concrete for the 40-foot-high footbridge when the collapse set off a scene one EMT described as "sheer chaos." Those nearby described a “loud thud” that “lasted for about 15 seconds,” followed 10 minutes later by sirens.
"It sounded like when they are doing construction on a building and they throw garbage off the top," one witness said. "It was like they were dumping huge material off a building and it echoed in a dumpster."
