Good morning
graphhopper does not recognize the pedestrian and bike path between “Via Caduti delle Reggiane” and “Via Piero Montagnani Marelli”. I have traveled this route by bicycle and I can guarantee that the pedestrian and cycle path exists.
There are two problems: Problem 1 was an unconnected node in the OSM data. This one I just fixed. The second problem is that this way is tagged only as highway=footway, without any bicycle tags. You need to fix this problem by your own as I cannot guess what kind of cycleway tagging would be correct (e.g. bicycle=designated or highway=cyclewaywith foot=yes …)
