ARCUS Atlas record
Ponte Allaro
Total collapse of the northbound carriageway of the Ponte Allaro on the SS106 Jonica national road near Marina di Caulonia (Reggio Calabria, Calabria) on 1 November 2015, during the major flood that struck the Locride area (the 'alluvione della Locride', 31 October–2 November 2015). The Allaro river overwhelmed the bridge, causing the collapse of the 'ponte monarchico' (the older of the two parallel structures). The remaining partial structure was demolished on 6 November 2015 for safety reasons. ANAS appaltò reconstruction works of €2.5 million in December 2016; the new bridge was opened in December 2020. No fatalities directly attributed to this specific bridge collapse (though the broader flood claimed multiple victims in the area). Piena della fiumara Allaro (alluvione Locride, nov. 2015): crollo della corsia 'monarchica' del ponte SS106. Il successivo progressivo abbassamento dell'impalcato della corsia superstite durante le piene seguenti indica cedimenti fondali (scalzamento) come meccanismo probabile; nessuna perizia pubblica reperita.
