“Construction of the pedestrian bridge that collapsed and killed six people in the Miami area was behind schedule and millions over budget, in part because of a key change in the design and placement of one of its support towers,” according to a report by The Associated Press.

An eyewitness filmed the pedestrian bridge at Florida International University in Miami after it had collapsed onto a highway on March 15.

“I was in my room and I heard the loudest boom in my life,” said Gabriela Collazo, who filmed the video. “I thought it was a crane that fell, but I go out in my balcony and see this absolutely horrific scene. I just want to send prayers to all those involved and those families who lost a loved one today.”
