Greek National Road 33 is a single carriageway road in southern Greece. It connects Patras with the Greek National Road 74 near Levidi, passing through the western and southern foothills of Mount Erymanthos.
Route
The EO33 is officially defined as a northwest–southeast road within the Arcadia and Elis regional units: the EO33 runs between Patras to the northwest and Levidi to the southeast, passing through Tripotama. The EO33 connects with the EO8 and EO9 in Patras, and the EO74 near Vlacherna. ==History==
History
Ministerial Decision G25871 of 9 July 1963 created the EO33 from the old EO56, which existed by royal decree from 1955 until 1963, and followed the same route as the current EO33. The EO33 follows most of the historic EO111, which existed from 1928 to 1955: however, the EO111 deviated from the EO33 between and Tripotama, going via Kleitoria and Aroania, instead of Paos. ==References==
