ARCUS Atlas record
Bridge over SP21
Total collapse of the bridge on the SP21 provincial road near Adelfia (Bari, Apulia) on 23 October 2005, triggered by the same catastrophic rainfall event that destroyed the Cassano delle Murge bridge and caused the Eurostar 9410 derailment. The collapse flooded many roads and contributed to the isolation of parts of the Bari hinterland. No fatalities directly attributed to this specific collapse. Database ponti fluviali danneggiati di D'Angelo, Ballio & Ravazzani (2025), IJDRR 'Geomorphologic risk factors for river bridges', suppl. S3, record P123 (accuratezza diagnosi dec=0.5): processo = erosione del rilevato in alveo/golena; componenti danneggiate = rilevato di accesso; evidenza di sormonto = yes.
