Malpertugio Viaduct, Road viaduct on A20 motorway in Sicily, Italy

Malpertugio Viaduct is a road bridge on the A20 motorway that crosses a valley in Sicily. The structure carries two lanes of traffic connecting different regions of the island.

The two parallel prestressed-concrete viaducts were completed in 1996, built with prefabricated box-girder segments launched by a launching girder. Each deck carries two lanes plus a hard shoulder, with seven spans of 61 + 5 × 110 + 61 m over a 672 m length. At 122 m high, it is the tallest viaduct on the A20, which continues into the 1,765 m Sant'Ambrogio tunnel.

The viaduct takes its name from the Malpertugio locality beside Cefalù. Drivers cross it on the A20 between the long Sant'Ambrogio tunnel (1,765 m) and open views over the Mediterranean below, so the crossing is a brief, high passage along the coastal route.

Travelers using this motorway section should be aware that tolls apply and nighttime lighting is limited in some areas. Plan your journey carefully, especially during adverse weather or low visibility conditions.

The structure forms part of the E90 European route and facilitates international traffic flow. Its location makes it a key crossing point for those traveling through northern Sicily.
