On August 14, 2018, a section of the Morandi Bridge in Genoa, Italy, gave way, dropping vehicles and tons of concrete 50 meters onto the riverbed below and killing 43 people. This episode of the engineering series What Went Wrong reconstructs the collapse hour by hour, using survivor accounts and interviews with structural engineers who examine the bridge's original 1967 design by Riccardo Morandi, a cable-stayed structure that relied on tensioned concrete rather than exposed steel cables. Engineers walk through decades of corrosion reports, patch repairs, and warnings about the bridge's aging stay cables that went unheeded, weighing design flaws against maintenance failures. Firefighters describe the rescue operation that followed, pulling survivors from crushed vehicles and collapsed rubble against the clock. The film uses footage of the wreckage, diagrams of the bridge's stress points, and archival material of the structure before its fall to lay out how a landmark meant to last generations came down in seconds, and what the disaster changed about how Italy inspects its aging infrastructure.
