The designation of this highway is currently "footway" and it claims the source, as follows:  source:designation=suffolk_county_council_prow_gis_data
I couldn't understand how to check the source to see exactly what the previous mapper meant, but from limited local knowledge + aerial imagery, I'm wondering if a different designation would be more appropriate on OSM here? This 'footway' clearly links the road to a farm and other buildings, and motor vehicles are shown nearby which I think could only have accessed via this "footway"? highway=service or highway=track seems more appropriate to me, but could someone please advise?
