Beginning of the surveying works for the erection of Tsakona Bridge, Arcadia Country, Greece

The surveying works for the erection of Tsakona Bridge T4 have begun. The Tsakona bridge will be the second largest in Greece, after the Rio-Antirrio Bridge, and is considered as one of the largest arch bridges worldwide. It is the last work that remains to complete the section Paradeisia – Tsakona axis Tripolis – Kalamata (made by the State and will be delivered to the consortium Moreas).

The bridge comprises of two abutments and a pier. The 300 meter crossing is partially bridged (40m) with a prestressed segment and the rest (260m) is covered with two steel arches from where the bridge’s mixed deck is hanging.

The arch bridge reaches 400 meters in length and connects an area where a large landslide took place in 2003. It is a structure of extraordinary complexity, both in terms of foundation, as well as superstructure.

The bridge is supported at three points: one at each end (abutments) and one that is closer to the top of pier. This last is the most important: it is basically a giant ‘prefab’, which will ensure the stability of the bridge. From the pier start the arch of the bridge, a maximum height of 30 meters, which leads to the opposite edge. The two arches, one on each side, supported the metal part of the bridge on which the road is located.
