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.
At least eight vehicles were trapped in the wreckage of the
bridge
and at least 10 people have been transported to hospitals, officials and doctors told news conferences.
Witnesses told local media the vehicles were stopped at a traffic light when the
bridge
collapsed on top of them at around 1.30 pm. ET (1730 GMT).
"We're working our way into the pile trying to create holes that we can actually physically see," Miami-Dade Fire Department Division Chief Paul Estopian told reporters.
At one point, police requested television helicopters leave the area so rescuers could hear for any sounds of people crying for help from beneath the collapsed structure, CBS Miami television said.
Complicating the rescue effort was the uncertainty about the integrity of the
bridge, parts of which remained off the ground, much of it inclined, local media reported.
The 174-feet (53-meter) long
bridge
connects the university with the city of Sweetwater and was installed on Saturday in six hours over the eight-lane highway, according to a report posted on the university's website. "If anybody has done anything wrong, we will hold them accountable," said Florida Governor Rick Scott, at a Thursday night press conference, after his office issued statement saying a company contracted to inspect the
bridge
was not pre-qualified by the state.
The
bridge
was intended to provide a walkway over the busy street where an 18-year-old female FIU student from San Diego was killed while trying to cross last August, according to local media reports.
Students at FIU are currently on their spring break vacation, which runs from March 12 to March 17.
'A MIRACLE'
Student Aura Martinez was having lunch in a nearby restaurant with her mother when a waitress told her the
bridge
had collapsed. She ran outside and helped pull a woman out of her car, most of which was flattened by the
bridge.
"Her car, it was literally a miracle of God, her car got squished by the
bridge
from the back, so she was able to get out and she was on the floor and it was just very traumatic," she told the local CBS affiliate.
To keep the inevitable disruption of traffic associated with
bridge
construction to a minimum, the 174-foot portion of the
bridge
was built adjacent to Southwest 8th Street
using a method called Accelerated
Bridge
Construction (ABC). It was driven into its perpendicular position across the road by a rig in only six hours on Saturday, according to a statement released by the university.
The $14.2 million
bridge
was designed to withstand a Category 5 hurricane, the most dangerous
measure by the National Hurricane Center, and built to last 100 years, the university said.
The National Transportation Safety Board was sending a team to investigate why it collapsed.
President Donald Trump thanked first responders for their courage on Twitter. Along with Governor Scott, US Senator Marco Rubio went to the scene of the collapse.
Munilla Construction Management, which installed the
bridge
was founded in 1983 and owned by five brothers, according to its website. In addition to its Florida operations, the company also has divisions in Texas and Panama and employs 500 people.
"Munilla Construction Management is a family business and we are all devastated and doing everything we can to assist," the company said in a statement.
FIGG Engineering said it took part in the
bridge
project and the collapse was a first in its 40-year history.
Both companies said they would cooperate fully with investigators.
Colorado-based engineering company BDI said in a tweet on March 12 that it was "thrilled" to have conducted structural monitoring during the "spectacular" process of moving the
bridge
into place. The company removed the tweet on Thursday and said in a statement it did so out of respect for individuals affected by the collapse.
Scott's office said FIU picked a firm that was not pre-qualified to check the design of the
bridge, which was required because it was such a long pedestrian
bridge
and other unique characteristics.
"The firm selected, Louis Berger, was not FDOT pre-qualified for this service, which is required under FIU’s agreement with the state. FIU’s design build team is responsible for selecting a pre-qualified firm and ensuring this process is followed," the governor said in a statement.
Officials at the Miami office of global engineering services firm Louis Berger were not immediately available for comment.
