The National Transportation Safety Board (NTSB) this week released around 6,300 pages of reports that examine the role of each contractor in the construction of the Florida International University (FIU) pedestrian bridge that collapsed and killed six people in March 2018.
A number of findings have been reported from various news sources as to some of the findings in these documents. For instance, the Miami Herald reported that the chief engineer for the Florida DOT (FDOT) wrote in a letter to the NTSB that FIU and its contractor were responsible for asking the state to close down the roadway beneath the bridge while crews repaired cracks in the bridge—something FIU never did.
Additionally, the Associated Press reported that a Federal Highway Administration assessment released with the documents found that FIGG—the bridge's designer—made significant errors in its design calculations for the bridge. The assessment attributes the cracking found in the bridge structure to the design errors.
