Why Bridges Collapse

In 2018, Italy’s Morandi Bridge collapsed, tragically killing 43 people. For 50 years, the iconic bridge had withstood the elements—and stress from ever-increasing traffic. What went wrong that fateful day? And how can new engineering technology protect bridge infrastructure to prevent such tragic failures in the future?

In August of 2018, an 800-foot section of Genoa, Italy's Ponte Morandi Bridge collapsed, killing 43 people. Two survivors reflect on the event.

In a single-point bridge failure, one component breaks and brings down an entire structure. See how this happened 52 years ago to West Virginia’s Silver Bridge.
