Yeah, it is the extension of Ionia Odos. It will be constructed here because there were earthworks done in 2017 for the future motorway.

Wikipedia says that the road is EO1β and A122. EO1β is for the trunk road and A122 is for the motorway.

Renamed the part in EO6 (Larisa - Trikala) to A4 because it has been decided to build a motorway there. In 2015 parts in EO6 were upgraded to a motorway so this would be used for the new motorway 4.
