A newly erected pedestrian bridge spanning several lanes of traffic collapsed at Florida International University on Thursday, killing four people, Miami-Dade County Fire Chief Dave Downey said.

Emergency personnel with sniffer dogs searched for signs of life amid the wreckage of concrete slabs and twisted metal after the 950-ton bridge crushed vehicles on one of the busiest roads in South Florida.
