Crews Work Overnight to Find Victims of FIU Bridge Collapse

At least  six people were killed  after a 950-ton pedestrian bridge at Florida International University in Miami collapsed Thursday, crushing a number of cars underneath.

Emergency crews worked  through the night , searching for possible victims.

Police say at least nine people were transported to hospitals.

The bridge was still under construction and planned to be finished in 2019.

The so-called  "instant bridge"  had been rapidly installed in just hours Saturday after being built nearby.

U.S.

Sen.

Marco Rubio  posted on Twitter  that the bridge's suspension cables were being tightened Thursday when it collapsed.

The National Transportation Safety Board is  starting its investigation  into the collapse Friday, and Florida Gov.

Rick Scott said any wrongdoers would be held accountable.

According  to the university , once finished, the $14.2 million bridge was designed to withstand a Category 5 hurricane and last for more than 100 years.  Additional reporting from  Newsy affiliate CNN .
