A preliminary report released on Wednesday on the fall of the pedestrian bridge last March in Miami reveals that the specialists of the National Board of Transportation Safety (NTSB) of the USA investigate cracks that appeared days before the collapse.
In the four-page report, which does not determine the causes of the fatal accident that claimed the lives of six people, it is noted that days before the fall of the pedestrian bridge, cracks appeared in diagonal beams at the north and south ends of the bridge. structure.
The cracks appeared even before the 53-meter-long pedestrian crossing was placed on top of the columns, at its location on the campus of the International University of Miami (FIU) and that would connect with the suburb of Sweetwater, as it emerges of the report that EFE had access to.
“The NTSB will conduct an additional forensic examination of several structural components of the bridge and destructive testing of multiple samples of cores and steel,” the report said, which states that the collapse is under investigation and that the agency expects to determine the causes of the accident.
The collapse of the bridge, which occurred in broad daylight on March 15, totally or partially impacted eight vehicles, seven of which were occupied, leaving one worker and five passengers dead, and eight injured.
The construction, promoted by the FIU to give security to students who had to cross Calle Ocho, used the so-called method of “accelerated construction” for its realization, which seeks to reduce the interruption of traffic during construction.
The NTSB investigators note that on the day of the fall a team of workers was “retensioning” one of the diagonal beams that connected the structure to the end brackets facing north.
The fall of the bridge, which was planned was ready in 2019, has caused family members of the victims to file civil suits.
As reported in a FIU statement, the final report is not expected to be ready in “several months.”
