Problem routing along one section of a cycle path

Can anyone see what is wrong routing a section of the Sustrans cycle route 403 northwards from Calne to Chippenham UK near A4 crossing? Acts as though route blocked but no evidence of it. Only seems a problem with Openstreet maps?

Thereā€™s a small gap in Chippenham, but I presume you arenā€™t asking about that. Can you link to something that gives an incorrect route? It might just be a router being slow to update its data.

I donā€™t see a problem per se, itā€™s probably just that the bike routing profiles youā€™re using on osm.org prefer paved minor roads to cycleways with ā€œintermediateā€ smoothness and an ā€œunpavedā€ surface.

Thanks. You have identified the problem. I had set profile to ā€˜roadā€™ on connect which normally works fine on cycle paths . Tried ā€˜gravelā€™ which gave same problem but profile ā€˜mountain bikeā€™ works! I wouldnā€™t say the cycle path was a motorway but seemed perfectly ok on a touring bike

However a quick glance at the descriptors for the cycle path section that works with ā€˜roadā€™ is the same for the section that doesnā€™t work. Why?

What might help would be to link to the actual way ID in OSM that itā€™s avoiding - zoom right in at osm.org, and then use ā€œquery featureā€ (the arrow / question mark icon) to see which way itā€™s avoiding.

One problem that it might be is that something is using ā€œGerman trunk road rulesā€ (that you canā€™t walk or cycle on what theyā€™d tag as a trunk road). That affects at least one of the routers on osm.org, and unfortunately also affects foot routing even if a sidewalk is mapped.

I donā€™t know what Garmin Connect is using internally, but I do know that Garmin uses OSM POIs extensively now. I also know that the Garmin GPSMAP65s in my pocket is infected with the same ā€œGerman virusā€ - in this case entirely my fault as Iā€™ve not amended routing rules for trunk roads from the mkgmap default, which apparently has the same ā€œfeatureā€.

Thanks for the response. I am still finding my way so your query check may be beyond my skills at the moment. . The section is a cycle path which is described as far as I can see is exactly as preceding section that the road profile accepts. surface = intermediate which should be ok for road cycling. I am considering reinstating the problem section so see if it makes a difference?
