The Silver Bridge Collapse occurred on December 15, 1967, when a suspension bridge connecting Point Pleasant, West Virginia, and Gallipolis, Ohio, fell into the Ohio River. The disaster was caused by a failure of a single eye-bar in the bridge's chain, which led to a catastrophic chain reaction. The collapse resulted in the deaths of 46 people. Following the incident, investigations revealed that the bridge had structural deficiencies and was not adequately maintained. The tragedy prompted changes in bridge safety regulations and inspections across the United States, highlighting the importance of infrastructure integrity to prevent similar disasters in the future.
