The most recent warning came in October 2017, when Carmelo Gentile, a structural engineering professor at the Politecnico di Milano, sent results of structural integrity tests to Autostrade per l’Italia, the bridge operator, and the central government’s highways agency. Gentile warned of troubling signs of corrosion or other possible damage to the southern bridge supports.

These supports ultimately failed and collapsed a portion of the bridge, killing 43 people and making 150 residents homeless. In all, more than 600 homes were destroyed by the collapse. Countless more people rely on the major throughway in and out of Genoa.
