FIU pedestrian bridge install left it vulnerable to collapse, WTH

AI Thread Summary
The recent collapse of the pedestrian bridge in Miami, which had been installed just days prior, has raised significant concerns regarding its engineering and construction processes. Experts suggest that the bridge was vulnerable to collapse during its installation phase, particularly as it was undergoing pre-opening stress tests when the failure occurred. Florida Senator Marco Rubio noted that the cables were being tightened at the time of the collapse, indicating potential mismanagement during construction. There are speculations about whether the failure was due to a design flaw, a construction error, or possibly a manufacturing defect, with some pointing to cracks reported two days before the incident as a critical warning. The tragedy emphasizes the need for thorough investigation into the engineering practices and safety protocols surrounding such structures.
