MILAN (AP) — Family members of the 43 people killed when Genoa’s Morandi highway bridge collapsed nearly eight years ago are expected to pack a courtroom Thursday for verdicts in the trial of 57 defendants charged in a disaster that exposed deep failures in the maintenance of Italy’s infrastructure.

The defendants include former executives of highway operator Autostrade per L’Italia, experts from its engineering company SPEA and former officials from Italy’s Infrastructure Ministry.
