In Openstreetmap, I just modified the pedestrian crossing which was not in tunnel mode, could the fact that the pedestrian crossing was not in tunnel mode create a conflict with the highway?
there's something very strange in MFN data. When I start on N10 nearly underneath the highway A8 and want to drive to A8 where the bridge ist above N10 (direction east), i get an 1200 meters track on OpenStreetMap site:
MFN will not go across the river, and when I set the target a bit more to the west of the river, I get a 420 Kilometers track goin to Liege and coming back ...
Junction lanes are not connected to N10, and some parts of the highway are not connected to each other. I guess it wasn't you creating this fault - on OpenStreetMap site everything seems to be ok.
It seems to me that the problem comes from the pedestrian path that crosses the highway, I modified the pedestrian path yesterday to put it in tunnel mode, we will have to see what happens after updating the map
Tried again, no routing across the river. West bank is shown in blue, east bank is that small pink line (why pink?) compared to openstreetmap.org. Beetween those lines is shown as normal ground - should be water (blue) there. And there's a "crack" in the highway - when I want to create a route on the highway from one bank to the other - no way. Both directions.
Crossing the pedestrians tunnel on the west by highway is no problem.
