Petroso Bridge 1974 was an arch bridge that was located across a deep gorge along the original A3 motorway that was completed in a Frankenstein-like fashion in bits and pieces throughout the 1960s and 1970s. Petroso Bridge was replaced in 2016 with a weathered steel beam span during a major overhaul and widening of the motorway.
the Tanagro Bridge had a healthy 36 year lifespan before it was bypassed and removed in 2010. The main rib of the arch followed a more natural cantenary curve with an unusually low arch span to rise ration of approximately 2:1.
The new Tanagro 2010 Bridge was built a few hundred meters downstream of the old concrete arch and consists of a pair of weathered steel beam spans of approximately 100 meters.
Several other nearby spans that were replaced in the early 2000s include Tanagro, Lontrano, Sant'Onofrio and Favazzina beam bridges.
