ARCUS Atlas record
Bridge over Stura di Lanzo stream
Total collapse of a municipal bridge over the Stura di Lanzo near Ala di Stura (Torino) on 13-16 October 2000, as part of the catastrophic alluvione. Documented in the ARPA Piemonte official report (Valli 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. D'Angelo, Ballio & Ravazzani (2025), 'Geomorphologic risk factors for river bridges', IJDRR, database supplementare S3, record P017 (dec=1, ciclopedonale, crollo totale, coordinate coincidenti con la scheda): processo = carico idraulico sulla struttura; componente = impalcato. La scheda indica tipologia 'Municipal': discrepanza tipologica da verificare (Ala di Stura, piena dello Stura, ott. 2000).
