ARCUS Atlas record
Barberino bridge
Total collapse of a national road bridge over the Trebbia river near Bobbio (Piacenza, Emilia-Romagna) on 14 September 2015, triggered by the severe flooding of the Trebbia during intense late-summer rainfall. The Trebbia is known for its powerful flash floods in the upper valley. No fatalities or injuries were reported. The medieval Ponte Gobbo (humpback bridge), a symbol of Bobbio, survived the event despite heavy flooding around it; the collapsed structure was a modern RC road bridge. Il ponte di Barberino (arco in muratura anni '50) cedette per la spinta dell'acqua durante la piena 'cinquecentenaria' del Trebbia; fonti locali segnalano anche il degrado manutentivo pregresso del manufatto. Nessuna perizia pubblica reperita. [Il database Polimi (D'Angelo et al. 2025, S3, record P080, dec=1) classifica invece il processo come: erosione verticale (scour).]
