ARCUS Atlas record
Bridge over Gesso stream
Total collapse of a cycle-pedestrian bridge over the Gesso stream near Roccavione (Cuneo, Piemonte) on 15 July 2002. Total collapse during the major summer flood that struck the Valle Gesso on 15 July 2002. The Gesso torrent overflowed destroying multiple bridges in a single day. The Valle Gesso is chronically flood-prone: major alluvioni struck in 2002 and again in October 2020 (which destroyed kilometres of roads and multiple bridges near Entracque, Valdieri and Roccavione). No fatalities or injuries were reported from this specific collapse. Database ponti fluviali danneggiati di D'Angelo, Ballio & Ravazzani (2025), IJDRR 'Geomorphologic risk factors for river bridges', suppl. S3, record P111 (accuratezza diagnosi dec=1): processo = erosione laterale di sponda; componenti danneggiate = spalle, rilevato di accesso; evidenza di sormonto = no.
