Highways in Greece Motorways National roads

A national road (Greek: Εθνική Οδός) is a class of all-purpose trunk roads in Greece. They are less important than a motorway but more important than a provincial road. The layout of the national road network varies a lot, ranging from fast multi-lane dual carriageways to twisting two-lane single carriageways.

The current system of national roads in Greece was created in July 1963,^[1] and have been updated many times since then. Most national roads have route numbers that begin with "EO",^[2] non-continuously from EO1 to EO99, but some (such as Thessaloniki Inner Ring Road) have no number.

A presidential decree of 28 June 1928 created the first known national road network in Greece, consisting of roads numbered EO1 to EO198:^[3] this lasted until 9 August 1955, when a royal decree created the second network with roads numbered EO1 to EO95, as well as the first to cover the current territory.^[4] The second network was itself replaced by Ministerial Decision Γ25871/1963 of 9 July 1963, which established the first 84 national roads of the current (third) network, numbered non-continuously from EO1 to EO99.^[1]

In 1995, additional sections of national road were added by Ministerial Decisions DMEO/e/oik/827/1995 (for the islands),^[5] DMEO/e/oik/779/1995 (for the Peloponnese),^[6] and DMEO/e/O/1308/1995 (for the rest of Greece),^[7] although not all of them were numbered. The decrees also subdivided the national road network into three categories: basic, secondary and tertiary.

In 1998, the National Statistical Service of Greece (ESYE, now the Hellenic Statistical Authority) added more sections of national road, but the numbers in the list were for statistical purposes only.^[8]

For national roads first introduced in 1963, destinations that did not appear in the original list (or were added later) are in italics.

Current national road marker

Old national road marker

National road markers consist of a blue rectangle with a white border and white numerals: the marker design is a recolour of the marker for the German Bundesstraße. The current design was introduced in 2003, as part of the Guidelines for the Design of Road Projects (Greek: Οδηγία Μελετών Οδικών Έργων, ΟΜΟΕ):^[54] it replaced the original design introduced in 1974, which consisted of a white shield with a blue border and blue numerals.^[55]

National roads markers rarely appeared on direction signs, which usually show just the destinations and distances. In 2003, the Guidelines for the Design of Road Projects provided for the use of national road markers on motorway signs.^[56]

From 28 June 1928 to 9 August 1955, the EO111 was a national road that ran between Tripoli and Lygies [el] (south of Patras), via Levidi and Tripotama, with the section between Lygies and Patras being part of the EO103. The historic EO111 is today part of the EO33 and EO74, although the EO111 deviated from the route of the EO33 between Pangrataika Kalyvia [el] and Tripotama, via Kleitoria and Aroania, instead of Paos:^[3] however, the EO111 is still used locally to refer to the national road between Tripoli and Patras.^[57][58]
