The Tsakona Arch Bridge (Greek: Τοξωτή Γέφυρα Τσακώνας) is one of the world's longest multi-span arch bridges. It crosses the Tsakona Valley and it spans a dangerous location near Megalopoli, where in the last decades, there have been many landslides.[1][2][3]

Construction

The Tsakona Arch Bridge, with a length of 490 meters,[1] was the last work that remained for the section Paradeisia – Tsakona axis Tripolis – Kalamata to be completed (made by the State and will be delivered to the consortium Moreas). As stated in the "Courage" by the project leader Nikos Donas, this bridge was one of the most difficult engineering projects, after the Charilaos Trikoupis Bridge. Τhe project's cost was budgeted at €94 million but there were unjustifiable overruns, the total cost arriving at €131.5 million.[4]

The bridge is supported at three points: one at each end (abutments) and one that is closer to the top of the pier. This last is the most important: it is basically a giant 'prefab', which ensures the stability of the bridge. From the pier starts the arch of the bridge, with a maximum height of 30 meters. The two arches, one on each side, support the metal part of the bridge on which the road is located.[5]

Its construction started in 2008[1] and was opened for traffic in January 2016.
