A portion of a motorway bridge connecting the coastal city of Savona to Turin collapsed on Sunday (November 24).
The collapse followed a massive landslide, caused by bad weather, which hit the bridge from a nearby mountain, Liguria Region president Giovanni Toti was quoted as saying by ANSA press agency.
Heavy rains have caused widespread flooding in northern Italy this month.
No casualties have been reported though Toti said he could not exclude that cars were involved.
A spokesman for SIAS, the company operating the A6 motorway, could not confirm any details and said the toll road operator was carrying out investigations to assess the situation.
He said the 50-metre (164 foot) long viaduct was located just outside Savona. Motorway circulation was stopped in both directions, though just one of the two carriageways collapsed.
Liguria is the same region where a motorway bridge collapsed last year, in the city of Genoa, killing 43 people. Known as the Morandi bridge, it was operated by Autostrade per l’Italia, a unit of infrastructure group Atlantia.
The collapse of the Morandi bridge shocked Italy and is still a very vivid memory for Liguria residents.
“I saw that the bridge was no longer there and I was immediately taken by despair”, resident Antonella Bruzone said.
