Demolition work is expected to begin in September to remove the remaining sections of the Polcevera Viaduct in Genoa, which partly collapsed on August 14, killing 43.

Local news reports quote investigators who say the danger of other parts of the bridge collapsing is high. A photo shows one of the bridge's remaining concrete pillars resting on nearby buildings.

The bridge carried the A10 motorway across a river, railroad tracks and numerous structures. It was built between 1963 and 1967 and was designed by Italian engineer Riccardo Morandi.

A member of the ministerial committee investigating the remains of the bridge says one of the remaining pillars is in worse condition than a similar pillar before it collapsed. The risk of collapse on parts of the bridge that remain standing is classified as 4 out of a maximum of 5, news reports say.

Removal is expected to begin with what is known as the east pillar, which has been heard creaking since the August 14 accident. Experts plan to demolish it using explosives and machinery, before moving to dismantle the final remaining pillar piece by piece.

Meanwhile Italy's Guardia di Finanza, the police branch which investigates financial crime, raided the offices of Italian motorway operator Autostrade per l'Italia in Rome, Florence and Genoa. Servers, as well as computers and smartphones belonging to the company's senior management personnel, were confiscated, reports say. The raid was ordered by the office of the public prosecutor in Genoa.
