Sfalassa Viaduct, Road bridge in Bagnara Calabra, Italy.

The Sfalassà Viaduct, also called Ponte di Bagnara, carries the A2 motorway over the Fiumara Sfalassà gorge above Bagnara Calabra. Its 376 m main opening is a steel deck supported by two inclined steel struts forming a Sprengwerk, split into spans of 110 + 156 + 110 m. The deck, a hollow box stiffened inside by Andreaskreuz bracing, runs about 250 m above the valley floor; the side piers and approach girders are reinforced and prestressed concrete.

The bridge was built in the early 1970s under engineer Silvano Zorzi and opened to traffic within a few years. Its construction was part of a broader effort to modernize transportation routes in southern Italy.

The viaduct won the CECM European Award three times during construction, in 1968, 1970 and 1972, a record no other structure has matched. Locals also call it Ponte di Bagnara, after the town below. Its name comes from the Fiumara Sfalassà gorge it crosses.

The bridge is part of the A2 Mediterranean Highway and carries regular traffic daily. Visitors should know that it functions as an active roadway, and nearby viewpoints offer the best opportunity to see the structure from a distance.

The Sfalassà Viaduct is the world's largest batter-post rigid-frame bridge, with a 376 m main opening split by two inclined steel struts into spans of 110 + 156 + 110 m. During construction it won the CECM European Award three times, in 1968, 1970 and 1972, a record still unbeaten.
