This road is tagged as primary_link and not as motorway (and never has been tagged as such).
To my knowledge, OSMAND checks for motorway and motorway_link (see https://github.com/osmandapp/OsmAnd-resources/blob/master/routing/routing.xml, section avoid_mototway)

If you use the pedestrian profile, it looks like OSMAND wants to avoid trunk and trunk_link as well. This road has been tagged as trunk_link earlier, in this case you might need to download recent data from this area.

Anyway, best ask at OSMAND issue tracker as this is not an error in the data: https://github.com/osmandapp/OsmAnd/issues
