Greek National Road 30

The EO30 is officially defined as an east–west road in Epirus and Thessaly: the EO30 runs between Arta in the west and Volos in the east, passing through Vourgareli, Trikala, Karditsa, Neo Monastiri, Farsala, Mikrothives [el] and Nea Anchialos.^[1] Between Neo Monastiri and Farsala, the EO30 runs concurrently with the EO3.

The EO30 connects with three motorways: the A1 at Mikrothives, A3 east of Karditsa and west of Sofades, and the A5 in eastern Arta.

On 20 December 2010, the EO30 was realigned between Aetos [el] and Pyli to pass through the newly-opened 1.5-kilometre (0.93-mile) long Gropas Tunnel (Greek: Σήραγγα Γκρόπας) west of Stournareika [el], bypassing a section of road via Neraidochori that was often blocked by snow during the winter.^[2]

Ministerial Decision G25871 of 9 July 1963 created the EO30 from all or part of the following short-lived national roads (listed from west to east), which existed by royal decree from 1955 to 1963:^[1][3]

• The old EO24, from Trikala to Neo Monastiri
• The old EO1, from Neo Monastiri to Farsala
• The old EO82, from Farsala to Mikrothives [el]
• The old EO16, from Mikrothives to Volos
