What caused the tragic 2018 collapse of Italy's iconic Morandi Bridge?
In short: This documentary investigates the structural failure of the Morandi Bridge, which resulted in 43 fatalities. By examining this disaster alongside other historical bridge collapses, the film explores the engineering vulnerabilities of modern infrastructure and the potential for new technologies to prevent future catastrophes.
The Morandi Bridge had served as a vital piece of infrastructure for 50 years, enduring both environmental stressors and the demands of steadily rising traffic volumes. The collapse prompted a critical look at how such structures fail, drawing on eyewitness accounts and expert analysis to understand the mechanics behind the disaster.
The investigation extends to other notable failures, including the Tacoma Narrows and I-35W bridge collapses. By analyzing specific components like gusset plates and the general principles of suspension bridge construction, the film highlights the ongoing challenge of maintaining aging infrastructure and the role of engineering innovation in ensuring public safety.
