Hello and welcome to OpenStreetMap!
It was me that forgot to clarify that that foot and bicycle access was permitted, back in 2022 - see https://map.atownsend.org.uk/maps/osm-deep-history/#/way/32493721 .  I've undone the duplicate cycle path here, since there isn't one, but clarified the access in https://www.openstreetmap.org/changeset/160542044 .
Hopefully that's all OK now?
Best Regards,
Andy
