Abridge on the 'Adriatica' State Highway 16 over over the Trigno River near Montenero di Bisaccia in Molise collapsed on Thursday after a wave of extreme weather hit central and southern Italy.
The highway was closed on Wednesday, when the bridge was put under observation after the river swelled and burst its banks amid torrential rain.
As a result road links to Abruzzo are effectively cut off.
The Carpino River has also burst its banks, flooding part of Provincial Highway 45 in the Carpinone area and the Pettoranello del Molise industrial zone near Isernia.
The levels of the Ofanto River in the north of the province of Bari are worryingly high too and there is an alert regarding Occhito Dam amid flooding in Carlantino, in the province of Foggia.
