Piacenza cable-stayed bridge, Railway bridge in Piacenza, Italy.

The Piacenza cable-stayed bridge is a railway crossing spanning 1343 meters over the Po River with two main towers rising roughly 60 meters high to support the span. The structure connects Piacenza and San Rocco al Porto, carrying high-speed trains across the water.

Construction began on 15 July 2002 with the laying of the first stone, attended by Silvio Berlusconi and Pietro Lunardi; the engineer was Mario Paolo Petrangeli and the cost 43 million euros. The bridge was inaugurated on 19 June 2006, then track and systems were installed. Regular service started on 14 December 2008, after a ceremonial Milan-Bologna run the day before.

The bridge carries the Milan-Bologna high-speed line across the Po between the hamlets of Bosco dei Santi, in Piacenza, and Mezzana Casati, in San Rocco al Porto. Its deck crosses the river at an angle of about 22 degrees to the current rather than perpendicular, a constraint tied to navigation requirements.

The bridge is in full train operation and can be viewed from the outside, such as from nearby riverbanks or road overpasses in the surrounding area. A good way to experience it is by taking a train journey across it or visiting the adjacent towns.

The bridge crosses the Po at an angle of about 22° to the perpendicular of the current, not square to the river. Its design was constrained by the Emilia-Romagna navigation authority ARNI, which required minimum clear spans of 70 m, and by the environment ministry, which blocked a single central pier. The deck also keeps a clearance of 6.8 m above the maximum navigable level.
