Of course I do not place nodes at the road-ditch intersections. But we have this
kind of intersections where a ditch is goind under a road through a concrete or
plastic pipe approximately every fine hundred meters on every single road we
have. Do you suggest that splitting the ways, making 2 meter long sections as a
"brigde=yes, layer=1" really makes sense? How ofter guessing that highway is
above waterway would fail?
