Hi,
I am confident that we will be fine with full and unabridged relations for unbroken highways like EO7, EO8 and EO9 (and of course, not EO1), as these roads are national-level: we are not dealing something as massive as the European Road Network, and a single relation, where possible (unlike EO1), will make the task of mapping the roads a lot simpler. If you have any issues about the alignment, I can resolve it easily.
As for Argos, the EO7 would go via the old station and through the ring road.
To be honest, what we really need is Alexis Tsipras to fix this whole system, without those “wish-list” entries, so that we do not have to do this complex guesswork.
