1974-2010
One of the few arch bridges that were constructed along the original A3 motorway that was completed in a Frankenstein-like fashion in bits and pieces throughout the 1960s and 1970s, 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 Petroso, Lontrano, Sant'Onofrio and Favazzina beam bridges.
You can see various views of the Tanagro implosion as well as several others along the A3 on Youtube:
