Promise and Disaster
In March 2018, Florida International University unveiled a pedestrian bridge in Miami meant to symbolize innovation and safety.
At 53 meters, it was built to connect campus with nearby neighborhoods. But just days after installation,
the bridge collapsed within seconds, crushing eight vehicles. Six people died and several were injured.
More Than Technical Failure
The collapse became a case study in engineering and management breakdowns.
Experts noted it was not just a mistake but “an avoidable disaster” fueled by blind spots, ignored warnings, and poor decision-making.
Unusual Design Choices
The bridge used a concrete truss design rarely seen in modern projects.
Forensic engineer Dr. Sean Brady explained: “If one of those members breaks, there’s nowhere for the load to go.”
Without redundancy, one weak point meant total failure.
Flawed Execution
Cold joints—concrete poured at different times—created hidden vulnerabilities.
A key instruction to “roughen” a joint for bonding was missing from drawings, slipping through peer review and into construction.
The replacement bridge now stands as both a safer passage and a stark reminder of responsibility.
