Greek National Road 9 (Greek: 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 220 km (140 mi), 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]
Ministerial Decision G25871 of 9 July 1963 created the EO9 from the old EO51, which existed by royal decree from 1955 to 1963, and also followed the same route as the current EO9.[4][2] In 1998, the Hellenic Statistical Authority created the EO9a as a branch of the EO9, from Kalo Nero to Tsakona [el], taking over some of the Messenia regional unit's Provincial Roads.[5]
