On March 15, 2018, 6 people were killed and 8 others were injured when an under construction pedestrian bridge collapsed in Florida.  Several months later, the National Transportation Safety Board (NTSB) released their preliminary report while conducting an official investigation. The NTSB later issued an “Investigative Update” to their preliminary report in August. In Mid-November, the NTSB released a 2nd investigative update, narrowing their root cause theories.
