Genoa-Saint George viaduct, Highway bridge in Genoa, Italy
The Genoa-Saint George viaduct is a highway bridge in northwestern Italy that spans 1067 meters across the Polcevera valley. Eighteen elliptical pillars rise 45 meters to carry the roadway, which measures 30.8 meters in width.
This crossing replaced the Morandi Bridge following its collapse in 2018, with work starting in 2019. The official opening took place on August 3, 2020.
The bridge is named after Saint George, the patron saint of Genoa, whose red cross appears on the city flag. Its official name was announced by mayor Marco Bucci on 21 July 2020, shortly before the inauguration. The structure carries the A10 motorway and European route E80, with a speed limit of 80 km/h, reduced to 60 km/h for vehicles over 12 tons.
Automated monitoring systems and dehumidification equipment protect the structure from salt-laden condensation. Photovoltaic arrays supply power for lighting and inspection tools.
The lighting was planned as 43 lamps, one for each victim of the 2018 collapse, but design and safety requirements reduced them to 18, mounted on masts along the roadway centreline that also carry aircraft warning lights. Four wheeled robots built by the Istituto Italiano di Tecnologia run on rails outside the deck to inspect its underside and clean the wind barriers and solar panels.
