The Florida International University Bridge Collapse
The Florida International University pedestrian bridge collapse shows what can happen when visible structural distress is discussed without decisive action being taken. On March 15th, 2018, a newly installed concrete bridge collapsed across a busy roadway in Miami, killing six people. The National Transportation Safety Board identified serious design-calculation errors, an inadequate independent review process, and failures to recognize the significance of rapidly growing cracks. Engineers, contractors, the university, and transportation officials met to discuss the cracking shortly before the collapse, yet the road beneath the bridge remained open. The main ethical question whether any of those groups had an obligation to close the road when the exact cause of cracking was still uncertain. The case demonstrates that engineers should treat unexpected structural behavior as a potential warning of failure rather than merely a construction problem, particularly when members of the public are exposed to the risk.
