The trial of 59 people facing an array of charges over the deadly collapse of a motorway bridge in the Italian port city of Genoa opened this morning in front of relatives of the victims.
However, the judge then adjourned for the summer.
The judge said proceedings would resume on 12 September and scheduled hearings up to July 2023. Given the complexity of the case, sessions are likely to continue beyond that date.
The Morandi bridge, operated by Atlantia's motorway unit Autostrade per l'Italia (Aspi), collapsed at the peak of the summer holiday season on 14 August 2018, killing 43 people and laying bare the state of Italy's crumbling infrastructure.
The defendants face charges ranging from multiple manslaughter to making false statements. They have all denied the accusations.
Amongst those in the dock are former Atlantia CEO Giovanni Castellucci, who is accused of endangering safety on the roads and wilful failure to take precautions to prevent disasters.
He faces a maximum sentence of 15 years in jail if convicted.
"I hope that a truth emerges that will be as objective as possible. Above all, I hope that no summary justice is carried out," said Guido Alleva, one of Mr Castellucci's lawyers.
The trial is taking place in the largest hall in the Genoa court, while a marquee with video screens has been set up outside to accommodate hundreds more members of the public and journalists who want to attend.
Prosecutors have compiled a list of 178 witnesses who they want to call, including Aspi's current CEO Roberto Tomasi and two former infrastructure ministers.
Legal sources said that many of the lawyers for the defendants dispute the findings of an expert report into the causes of the collapse that took a year to compile.
They could ask the court to annul the report and commission a new one.
"The trial is expected to be long and complex," said Egle Possetti, spokesperson for the victims' relatives committee, whose sister, brother-in-law, and two nephews died in the collapse.
"We hope that there will be no loopholes to interrupt the thread of truth and justice that has already emerged in the investigation," she added.
Judge Paola Faggioni, who in April ordered the trial, has also accepted a financial settlement proposed by Autostrade and its sister company SPEA to close the case against them.
The collapse caused a dispute between Atlantia, controlled by the Benetton family, and the government that ended last year with the sale of Atlantia's controlling stake in Autostrade.
In a document on the findings of the investigation into the disaster, prosecutors said that the collapse was triggered by the rupture of the load-bearing cables inside the stay of the bridge's ninth pillar, which were eaten away by a highly corrosive atmosphere over the 51 years of the bridge's life.
