Rio-Antirrio Bridge

The Rio–Antirrio Bridge, officially the Charilaos Trikoupis Bridge, is one of the world's longest multi-span cable-stayed bridges and longest of the fully suspended type. It crosses the Rion Strait between the Gulf of Corinth and Gulf of Patras, linking the town of Rio on the Peloponnese peninsula to Antirrio on mainland Greece by road. The bridge dramatically improves access to and from the Peloponnese, which could previously be reached only by ferry or via the isthmus of Corinth in the east. Its width is 27.2 meters, with two vehicle lanes per direction, an emergency lane, and a pedestrian walkway. The bridge is widely considered to be an engineering masterpiece, owing to several solutions applied to span the difficult site, including deep water, insecure materials for foundations, seismic activity, the probability of tsunamis, and the expansion of the Gulf of Corinth due to plate tectonics
