Hello,
I don't think that there is anything that suggests that https://www.openstreetmap.org/way/812960030/history is part of the public road network, is there? OS OpenData suggests not (just look at that layer in an editor) and the rights of way data suggests that the whole thing is actually bridleway: https://map.atownsend.org.uk/maps/map/map.html#16/50.9962/-0.1375/H/P .
