A8 motorway (Greece)

The A8 motorway, also known as the Olympia Odos (Greek: Ολυμπία Οδός), is a toll motorway in southwestern Greece, which connects Athens with Pyrgos and Patras via Corinth, spanning a total of 290 km (180 mi).

The motorway replaces Greek National Road 8A, which has been upgraded to modern motorway standards. The completion date was scheduled for 2014. Since April 2017, the entire motorway from Eleusis to Patras is fully operational. The extension to Pyrgos opened in 2025. The future extension to Tsakona near Kalamata is in the planning stages.
