Greek National Road 21 (Greek: Εθνική Οδός 21), abbreviated as the EO21, is a national road in western Greece. The EO21 runs within the Preveza regional unit, from Filippiada to Preveza.

Route

The EO21 is officially defined as a north–south road within the Preveza regional unit: the EO21 branches off the EO5 south of Filippiada and heads south to Preveza, passing through Louros and Nicopolis (for the EO19).[2] At Preveza, the road connects with the Igoumenitsa–Actium National Road (also the E55).[3]

History

Ministerial Decision G25871 of 9 July 1963 created the EO21 from the old EO20, which existed by royal decree from 1955 until 1963, and followed the same route as the current EO21.[2][4] The road became part of the secondary network in 1995.[3]
