Looking back, it probably is a highway=service, but I do not kniw the access.

I tagged it as road, because I was unsure what it really is when I walked there. At its beginning, it looks like a normal public residential road made of asphalt, but the surface it getting worse and worse towards the end, to  such an extent that i was unsure where it ended and where private property began. It also leads only to what appears to be a private property, yet without any signage prohibiting entry. So the locals probably dislike someone going there, as I also felt a bit intrusive to walk and map there as a foreigner, but I do not know if its illegal to walk or drive there without permission.
