Bridge over Stura di Lanzo stream

Total collapse of a municipal bridge over the Stura di Lanzo near Chialamberto (Torino) on 13-16 October 2000, as part of the catastrophic alluvione. Documented in the ARPA Piemonte official report (Val Grande di Lanzo area). Total collapse during the catastrophic alluvione of 13-16 October 2000 that struck over 50% of Piemonte, causing more than 1,800 documented damage events. The ARPA Piemonte report (2003) explicitly documents multiple bridge collapses across the Stura di Lanzo, Orco, Chisone, Dora Riparia, Dora Baltea and Po basins. The event is comparable in scale to the 1994 alluvione del Piemonte. No fatalities directly attributed to this specific collapse. Monografia 'Eventi alluvionali in Piemonte 2000-2002' (Regione Piemonte/ARPA, 2003): a Chialamberto, loc. Inverso, lo Stura ampliando la propria sezione in destra idrografica asporto' totalmente le difese spondali, distrusse cinque edifici e 'il ponte di accesso alla localita'' con la condotta principale dell'acquedotto della valle. L'associazione a questa scheda (tra le tre di Chialamberto) e' probabile ma non certa.
