Copious vehicles fall 45m (148ft), when a part of the bridge gave way during torrential rain on Tuesday.
Former Cagliari goalkeeper Davide Capello, who was driving on the bridge, escaped through the rear window with no serious injuries.
"I heard a dull noise, like a thud in front of me, and i saw the motorway pillars collapsing and the cars in front of me falling into a void".
"I have a deep sorrow for those who didn't survive. It is a tragedy. I can't believe a bridge can fall down in a modern society." He said.
A 12-month state of emergency has been declared in the Liguria region and on Saturday there will be a national day of mourning to coincide with the funerals of victims.
