Highway bridge collapses in Italy, leaving about two dozen dead

Genoa, Italy The sound of jackhammers reverberated through the night in this northern Italian city, where crews searched for survivors of a highway bridge collapse that left about two dozen people dead, officials said.

A major section of the bridge partially collapsed on Tuesday, sending vehicles hurtling toward the earth. Abandoned vehicles remain on the span, with one truck close to the edge. Some chunks of concrete are the height of a three-story building.
The search-and-rescue mission is expected to last for days, Emanuele Gissi, an engineer with the country’s fire service, told state broadcaster RAI News 24. Gissi said several people remain missing.

Teams with rescue dogs are aiding the effort.
Angelo Borrelli, head of the Italian Civil Protection Agency, said about 30 vehicles and several heavy-duty trucks were on the affected section of the Morandi Bridge, which lies to the west of the port city of Genoa, when it gave way.
Prime Minister Giuseppe Conte said 22 people are dead and another 16 people were injured, nine of them in serious condition. Separately, the office of the governor of the Liguria region said 26 people have died. Genoa officials declared two days of mourning.
According to police, violent storms were partly to blame for the disaster. Maintenance work also was underway at the time to consolidate parts of the bridge, according to motorway operator Autostrade. A bridge crane had been installed to allow the work to be carried out, the operator said in a statement.

“The works and the status of the viaduct were subject to constant observation and supervision,” the statement said. “The causes for the collapse will be the object of an in-depth analysis as soon as it will be possible to safely access the site.”
Conte said authorities were working on the theory the collapse was due to a “structural failure.”

The number of casualties is expected to grow as the rubble is removed, Borrelli said, but it is unlikely that anyone was underneath the bridge at the time of the collapse, he added.
Some 440 people have had to abandon their homes following the collapse of the bridge, the mayor of Genoa’s office said in a statement. Eleven buildings had to be evacuated and the number of people and buildings evacuated could rise as risk assessments are ongoing.
Vehicles line a part of the bridge that remains standing.

The incident at the bridge, a concrete structure opened in 1968, occurred about noon (6 a.m. ET) Tuesday, Italian state police said.
The A10, which runs across the bridge, is a major highway for residents and tourists in Genoa, connecting the city with the nearby airport, and a key route along the Mediterranean, linking the Italian coast with French coastal cities to the west.
The disaster occurred during peak tourist season — when many French tourists would have been using the highway — and one day before a national public holiday when many Italians travel to coastal areas.
Davide Di Giorgio was filming the heavy rain from the window of his office in Genoa when he saw part of the bridge crash to the ground.

“It is too early to say what caused the tragic collapse, but as this reinforced and prestressed concrete bridge has been there for 50 years it is possible that corrosion of tendons or reinforcement may be a contributory factor,” said Ian Firth, former president of the UK-based Institution of Structural Engineers, and a structural engineer specializing in bridges.
He added that there were “no obvious signs” as to what triggered the collapse at this time and that the storm and ongoing work on the bridge may or may not be relevant factors.
Genoa Mayor Marco Bucci said the bridge collapse was “not absolutely unexpected” but that he didn’t know the exact reason. When asked if he knew what had caused the bridge to collapse or if he knew if the bridge was undergoing repair work, Bucci said he wasn’t sure.
“It’s not my job to [know] that,” he said. “My job is to think about the future and work for the future of the city.”

“My role as the mayor is to make sure we have the correct infrastructure for the city and make sure that from the government we get the right amount of money in order to be able to set up the new infrastructure as soon as possible,” Bucci also said.
Demitrios Cotsovos, associate professor at the Institute of Infrastructure and Environment at Heriot-Watt University in Scotland, also urged caution before drawing any conclusions.
Engineers should be looking at the impacts of aging on the structural integrity of bridges such as this as well as “the potential impact of the environment and extreme weather conditions.”
