Greek National Road 73

The EO73 is officially defined as a north–south road along the east coast of Lesbos. The road starts in Thermi [el] to the north, heading south via Mytilene to Kratigos [el] in the south.^[1] The EO73 briefly runs concurrently with the EO36 between Mytilene and Panagiouda.^[2]

The national road was originally defined in 1955 as the EO70, and followed the same route as the current EO36.^[3] It was one of three sections of the 1955 national road network to not appear in Ministerial Decision G25871 of 9 July 1963 (the other being the current EO19 north of Neraida, and the Igoumenitsa–Actium National Road between Preveza and Vonitsa),^[4] but was later reinstated as the EO73 by Ministerial Decision DMEO/e/oik/827/1995 on 4 August 1995: at the same time, the EO73 south of Panagiouda was subclassified as part of the secondary network, and the section north of said village became part of the tertiary network.^[1]
