Rion-Antirion Bridge

Langan International served as the Lenders' Technical Advisor for this €1 billion multi-span cable stayed bridge spanning the Gulf of Corinth in Greece. The project was built by a French-Greek concession consortium led by VINCI. It consists of a 3.2 kilometer long deck constructed in an area of deep sea waters (65 m+), marginal soils and high seismicity. Construction involved dry docks, wet docks, deep dredging, underwater high-voltage cable relocation, soil improvement, tension leg barges, and off-shore techniques for the float-out and final positioning of the 90-meter diameter pylon bases.
