Greek National Road 7 (el|Εθνική Οδός 7, abbreviated as EO7) is a single carriageway with at-grade intersections in the Peloponnese region in southern Greece. It connects the cities of Corinth and Kalamata, via Nemea, Argos, Tripoli and Megalopoli. It has been succeeded in importance by the A7 motorway (Corinth–Tripoli–Kalamata).
The EO51 is officially defined as a road through the centre of the Peloponnese, running between Corinth to the north and Kalamata to the south, via Nemea, Argos, Tripoli, and Megalopolis.[1]
Ministerial Decision G25871 of 9 July 1963 created the EO7 from the old EO53, which existed by royal decree from 1955–1963, and also followed the same route as the current EO7.[2] [1] Until 1975, the entirety of the EO7 formed part of the old European route E92.[3]
