Some key points: - The bridge spans 2,252 meters over the Gulf of Corinth and connects the Peloponnese to mainland Greece. It was completed in 2004. - The environment presented challenges like deep water, weak soil, seismic activity, and strong winds. Foundations consisted of large caissons on reinforced soil with steel inclusions. - The cable-stayed bridge has a continuous and fully suspended steel-concrete deck. It is equipped with seismic dissipation systems including hydraulic dampers to absorb energy from earthquakes. - Innovative designs like the soil reinforcement and seismic protection
