A newly installed bridge collapsed on Florida International University’s campus Thursday, killing at least six people.
The collapse occurred at about 1:30 p.m. As of 5 p.m., a minimum of eight vehicles were trapped under the rubble. Some workers were on the bridge when it collapsed, but officials did not detail whether any of them were among the dead. Ten injured victims were transported to nearby Kendall Regional Medical Center.
More than 100 firefighters were on the scene working to find victims with the help of cranes and search dogs, and officials were working to stabilize the bridge.
According to an FIU press release, the 174-foot, 950-ton bridge was just installed “in a few hours” using “accelerated bridge construction” methods, which the university said “reduces potential risks to workers, commuters, and pedestrians and minimizes traffic interruptions.”
“Ironically, it’s a project for safety” that was constructed after a student died last year crossing that intersection, Florida Senator Marco Rubio said during an evening press conference.
