Ministerial Decision ΔΟΥ/οικ/5776/2015 (ΦΕΚ ΑΑΠ 253/21.12.2015) is the legal backbone for a the numbering system of a majority of motorways in Greece. However, there are some exceptions (as of March 2021), because of the current state of the road signs:
- The Α1 is not a motorway between Chalastra to Polykastro, because there is no central reservation.
- The Α24 is only a motorway between the Α2 and Papageorgiou interchange: everything south of the latter is an expressway.[1]
- The Α242 is also not a motorway.[2]
- The Α65 Egaleo Ring Road:
- The section north of Aspropyrgos Avenue is not downgraded, because the motorway signage still exists.[3]
- The section south of Aspropyrgos Avenue is not a motorway, because the connection with the ΕΟ8 at Skaramagas was never built.
Tempting it may be to counter those exceptions, but OpenStreetMap is not a crystal ball.
Mapping notes
Greece uses one relation per route number, even if consists of both motorways and expressways (like the Α24Α24).[a]
