Greek National Road 9 (Greek, Modern (1453-);: Εθνική Οδός 9, abbreviated as EO9) is a single carriageway with at-grade intersections in the West Greece and Peloponnese regions. It runs along the west coast of the Peloponnese peninsula, from Patras to Methoni via Pyrgos. Its length is around 220km (140miles), making it the second-longest national highway of Greece.
The government of Greece plans to replace the road by a new motorway. This will be a southern extension of the A5 (Ionia Odos), which will connect the Albanian border near Ioannina with the A7 (Moreas) north of Kalamata. It is expected to be completed in 2015.[1]
