ARCUS Atlas record
Bridge over Tanaro river
Total/functional collapse of Bagnasco's historic 'ponte romano' during the October 2020 Tanaro flood. Contemporary sources explicitly record the collapse; the official ARPA event report documents overtopping and damage to the upper arches, supporting overtopping/hydrodynamic action as the governing process. The affected component is retained as Deck / superstructure.
