LOS ANGELES (AP) — A portion of a parking garage being built to house buses in downtown Los Angeles collapsed on Friday, just minutes after nearly 200 construction workers were alerted that something was wrong and fled to safety, officials said.
A section of the structure measuring about 50 by 75 feet came crashing down just before 9 a.m. in the heavily congested area.
Minutes earlier, 180 people had been working on the structure, said Metropolitan Transportation Authority spokesman Marc Littman.
"Workers were pouring concrete in the upper parking deck of the northeast corner of the building," Littman said. "During construction we had pour watchers from below notice something was amiss. They immediately alerted workers to clear the area."
A few minutes later, the structure's second story, where 10 people had been working, collapsed onto the first level.
A Los Angeles Fire Department search and rescue team found no one trapped amid the rubble.
"Fortunately we have heard that all workers have been accounted for," Fire Department spokesman Erik Scott said.
Littman said construction was halted while investigators try to determine what caused the collapse.
