A horrific video of the Florida bridge collapsing has surfaced

Footage of the actual moment that the Florida bridge collapsed has been caught on a dashboard camera. The dash cam was on a car that was approaching the bridge at the time.

According to Pop Culture, the bridge collapsed on March 15, 2018. The video showed a man, who appeared to be working on the bridge, being tossed up as the bridge collapsed.

The Miami's Florida International University bridge collapse killed six people and injured 10 others. The dash cam video showed a man that was thrown into the air and then fell among the rubble as the bridge suddenly collapsed.

It's not clear if the man was a Structural Technologies VSL employee. He was among the six that were killed during the incident.

The footage also showed stunned motorists and passengers exiting their vehicles to rush to help after the collapse. An official cause for the collapse has not yet been declared.

Associated Press got documents that showed that in October 2016 the Florida Department of Transportation had ordered the Florida International University and its contractors to move one of the bridge's main support structures.

The structure was to be moved 11 feet north to the edge of a canal, which widened the gap between the crossing's end supports and required some new structural design. Engineers were also examining a crack on one side of the bridge.

Officials had previously stated that they knew of the crack in the bridge but believed it was not a safety concern. The bridge collapsed while a stress test was being performed to assess its strength.

"Once a design is completed, subsequent modifications tend to be suggested and approved without the full care that went into the original design. This has happened time and again in bridges and other engineering structures.”

The redesign involved the shifting of a tower but officials have suggested that there were many reasons for the collapse. Henry Petroski, a Duke University civil engineering professor, admitted that even seemingly minor changes in a bridge's design could lead to failures.

The project was already running $2.6 million over its $9.4 million budget. It’s finishing date being pushed back to January 2019 from July 2018.

The bridge's signature 109-foot-tall pylon was to be built atop a base at the northern end of the span. Its design would also contribute to the aesthetics of the bridge, which were said to be architectural marvels.

The bridge would have spanned a busy road and canal to connect the quickly-growing university to the nearby community of Sweetwater. In 2015, designers wrote in their proposal that it provided "spectacular views" for both pedestrians and drivers passing beneath it.

Alexa Duran was among the six that were killed as she was driving her car at the time of the collapse. Her friend, Richie Humble, who was in the passenger's seat, narrowly escaped the vehicle after it collapsed.

"I looked up, and in an instant, the bridge was collapsing on us completely. It was too quick to do anything about it," Humble stated.
