Rion-Antirion Bridge
Gulf of Corinth, Greece [INTERNATIONAL] · 1998–2004 · €630 million (construction cost), approximately £420 million (using 1 EUR = 0.66 GBP, 2004 conversion)
The judgement call
Account-gated at launchConsidered one of the most challenging bridge projects due to the adverse environmental conditions. - Innovative foundation design involved sinking large concrete caissons into the seabed and anchoring them to bedrock. - The bridge is designed to withstand a magnitude 7.0 earthquake, demonstrating advanced seismic engineering. - The project was delivered through a successful public-private partnership (concession agreement).
Key engineering challenges
Building in a deep water, seismically active zone with unstable seabed conditions. - Designing foundations to withstand significant seismic activity and potential tsunamis. - Constructing large piers on soft soil using innovative foundation techniques. - Protecting the bridge from potential ship collisions.
