I discovered another problem in the map: A road is there, but it cannot be routed over a mountain pass. (Openrouteservice has the same problem).
I investigated the junctions, but could not find any problems (like turn restrictions…)
I can confirm that the road can be travelled in both directions (in winter it may be closed depending on snow conditions).
Anybody knows the reason for this fault and how it can be fixed?
regards,
