Rio–Antirrio Bridge

TheRio–Antirrio bridge (Greek: Γέφυρα Ρίου-Αντιρρίου), 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.

The 2,880 m (9,449 ft) long bridge (approximately 1.8 miles) dramatically improves access to and from the Peloponnese, which could previously be reached only by ferry or via theisthmus of Corinth in the east. Its width is 28 m (92 ft) — it has two vehicle lanes per direction, an emergency lane and a pedestrian walkway. Its five-span four-pylon cable-stayed portion of length 2,252 m (7,388 ft) is the world's second longest cable-stayed deck; only the deck of the Millau Viaduct in southern France is longer at 2,460 m (8,071 ft). However, as the latter is also supported by bearings at the pylons apart from cable stays, the Rio–Antirrio bridge deck might be considered the longest cable-stayed "suspended" deck.

This bridge is widely considered to be an engineering masterpiece, owing to several solutions applied to span the difficult site. These difficulties include deep water, insecure materials for foundations, seismic activity, the probability of tsunamis, and the expansion of the Gulf of Corinth due to plate tectonics.
