The Rio–Antirrio bridge, officially the Charilaos Trikoupis Bridge after the statesman who first envisaged it, is one of the world’s longest multi-span cable-stayed bridges and the longest of the fully suspended type. It crosses the Gulf of Corinth near Patras, linking the town of Rio on the Peloponnese peninsula to Antirrio on mainland Greece by road.
