Bridge over Quazzola stream
Total collapse of a municipal bridge over the Quazzola stream in via Tecci near Quiliano (Savona, Liguria) on 4 October 2021, triggered by the extreme flash flood that struck the Savona hinterland during a severe rainfall event. The structure connected two residential properties across the stream and its collapse left two families isolated. The event occurred during a major flood that also caused the overflow of the Erro and Letimbro rivers and widespread infrastructure damage across the Savona province.
