GENOA, Italy (AP) — An Italian court on Thursday convicted the former CEO of Italy’s main highway operator and 31 others in the 2018 Genoa highway bridge collapse that sent vehicles plunging and killed 43 people, a disaster that exposed serious lapses in the maintenance of Italian infrastructure.

Dozens of family members of the victims packed the courtroom as Chief Judge Paolo Lepri read the verdicts against 57 defendants, including former executives and officials. Many relatives broke down in tears as the sentences were read.

The former chief executive of highway operator Autostrade per l’Italia, Giovanni Castellucci, was sentenced to 12 years in prison, the highest in the case after four years of trial and four hours of deliberations.

Castellucci’s lawyers said they would appeal, noting in a statement that as CEO, their client had relied on Italy’s leading engineers, and that a construction defect had not been detected by experts for over half a century.

“The suffering caused by the Genoa tragedy is immense and deserves respect. But the gravity of the event requires justice to remain based on individual responsibility, not the search for a scapegoat,” they said in a statement.

Also convicted were Autostrade’s former head of maintenance, Michele Donferri Mitelli, who was sentenced to 11 years in prison. The former CEO of the SPEA engineering company, Antonino Galatà, received five years and six months.

Defendants faced charges including negligence resulting in the collapse and manslaughter stemming from failures to maintain the bridge, which was part of a main route linking northern Italy with the French Riviera.

In all, 32 people were convicted and handed sentences ranging from 1 year and 11 months to 12 years. Others were either found not guilty, or lesser charges had expired under the statute of limitations.

“I think it is important that responsibility extends beyond those at the top. Autostrade, SPEA and the Transport Ministry all had roles to play. I hope the state’s responsibility also emerges clearly,” Egle Possetti, who heads a committee to preserve the memory of the bridge victims, told reporters outside the courthouse.

“I lost my sister, her two children, my brother-in-law and even their little dog. That’s where my determination comes from — to make sure they receive justice and that their deaths were not in vain,” she said.

Warning signs of defect were ignored
Shortly before noon on Aug. 14, 2018, a 200-meter (650-foot) section of Genoa’s Morandi highway bridge gave way during a rainstorm, sending dozens of vehicles plunging to the ground.

Images of the collapsed bridge were seen around the world and shocked Italians on one of Italy’s busiest travel days, as millions headed out for the traditional Aug. 15 Ferragosto holiday that marks the peak summer vacation season.

Prosecutors argued that years of maintenance neglect led to the collapse, and demanded combined sentences totaling nearly 400 years for all of the defendants. The defendants denied wrongdoing and say the fault was caused by a construction defect.

Considered an engineering marvel when it opened in 1967, the Morandi featured three A-shaped concrete pylons and concrete-encased stay cables.

Caruso, who represents the family members of three victims, said that the trial showed that warning signs about defects in the pylon that collapsed had existed for decades. He cited maintenance on the other two starting in 1993 that was never extended to the third.

“From 1993 onward, the problem was known. We had three identical pylons. Two had already shown the same defect, and no one seriously asked whether the third one had it as well,” Caruso said.

Autostrade had reached a deal to avoid trial
The current Autostrade chief executive, Arrigo Giana, issued a public apology Thursday in an open letter published in major Italian dailies.

“The actions and decisions of some people left indelible scars,’’ said Giana, who joined Autostrade as CEO last year. “Offering today the apology that was not made then is, for us, a moral imperative that goes beyond establishing legal responsibility and the course of justice toward the truth.”

Autostrade and its subsidiary reached a deal on corporate liability earlier in the proceedings, paying roughly 30 million euros ($34 million) in financial penalties. The agreement spared the companies from a trial as corporate defendants and potentially much harsher sanctions, including exclusion from public contracts.

The settlements were reached after the companies adopted new compliance procedures aimed at preventing similar accidents, and after victims were compensated.

A new bridge designed by Genoa-born Italian architect Renzo Piano opened in 2020, spanning a memorial to the victims of the Morandi Bridge collapse.
