II476 is NS
Debatable, it's rather diagonal.
Also, irrelevant. Clearly there isn't a grid here, but in places (N America) where there's strong grids routes don't necessarily meet at right angles (eg two N-S roads can meet each other) and so a N-S route can meet another one.
and II468 clearly heads to the west and east.
On the micro level, but
the road in general is very clearly more N-S orientated.
I'm fine with the status quo, if you are willing to take on board the general point (which was a lot of the issues I saw) that N-S roads can be concurrent with N-S roads, rather than the other routes needing to be perpendicular.
I'm gone with OSM/RSD now and let it end at II493 instead of II488 although 2011/12 GSV tells something different (and here)
That's fine. There's been some renumbering here. I trust your judgement on this.
