The former CEO of Italy’s motorway operator is among 32 people found guilty over the August 2018 collapse of Genoa’s Morandi bridge in a trial.
Giovanni Castellucci, who is already serving a six-year jail term for a 2013 road disaster, was given a 12-year sentence over the disaster.
Forty-three people died when the motorway bridge running through the city came down in a rain storm at the height of the holiday season, sending cars and lorries plummeting to the ground.
Another top motorway official, Michele Donferri Mitelli, has been given 11 years in jail.
BBC News journalist Davide Ghiglione explains how the disaster, and the subsequent criminal trial, unfolded.
