The [[Rio–Antirrio bridge]], carrying [[Ionia Odos|Motorway 5]], connects it with the [[Peloponnese]] peninsula.

==The port of Antirrio== [[File:Antirio-1981.jpg|thumb|right|Port of Antirrio (1981)]] The Port of Antirrio is served by ferries that carry traffic between the Peloponnese and northwestern Greece. Its significance has decreased since the opening of the [[Rio-Antirrio bridge]] in 2004. It is still in use as a ferry port for hazardous cargo and by users attracted by the scenic route or the lower fare for crossing the Rio-Antirrio strait. Adjacent to the port there is a lighthouse and the [[Antirrio Fortress|Castle of Antirrio]].
On the eastern pier of Antirrio port there is the Antirrio RTS (Regional Traffic Service)<ref>[http://hcg.gr/sites/default/files/docs/archive/texnikesprod.pdf Hellenic Coastguard, Technical specifications and description of the Greek National VTMIS system (pdf in Greek)]</ref> which is part of the national [[Vessel traffic service]] system of Greece (Officially called Vessel Traffic Management and Information System). The RTS of Antirrio includes a building with the necessary electronics/communication equipment and a sensors/radar mast of 20m height. On top of the mast there is a remotely controlled CCTV camera, VHF antennas and the antenna of the coastal surveillance and navigation [[radar]] GEM RT02-25D.<ref>[http://hcg.gr/sites/default/files/docs/archive/vtmisprdiav.pdf Hellenic Coastguard, Modernization of Greek National VTMIS system]</ref>
