Italia Viaduct, Highway bridge in Laino Borgo, Italy

The Italia Viaduct is a steel orthotropic-deck highway bridge on the A2 Salerno-Reggio Calabria motorway, spanning the Lao River gorge between Laino Borgo and Laino Castello. Its deck runs 1,161.4 m on 19 spans, and the road surface lies about 260 m above the river bed. The main steel deck is 425 m long and 21.6 m wide, carried on four piers with spans of 125, 175 and 125 m.

Three engineers designed the viaduct in 1964 following a national competition, and construction began shortly after in the Calabrian mountain region. The bridge was completed as part of the A2 motorway, which forms the main north-south route through the southern mainland.

The viaduct carries the A2 Salerno-Reggio Calabria motorway between Laino Borgo and Mormanno, crossing the Lao River gorge. Its steel orthotropic deck, 425 m long and 21.6 m wide, rests on four piers with spans of 125, 175 and 125 m. The structure was reopened to traffic in both directions on 26 July 2016 after modernization works, in the presence of Prime Minister Matteo Renzi.

Motorists cross the bridge daily on the motorway without being able to stop, as it forms part of a continuous highway route. Those wishing to view the structure from outside can see it from several points along the old roads below the viaduct.

For decades the viaduct held the title of Europe's highest bridge until a French structure took that position in 2004. The four main pillars support a steel deck section of 425 meters that floats over the deepest part of the gorge.
