That’ll be the Scot/E&W difference kicking in, then.
Here, Councils are required (by the Roads (Scotland) Act 1984), to publish a list of Public Roads (i.e. ones that they maintain). Anything not on the list is, by default, a Private Road (and therefore maintenance is not the responsibility of the Council).
(The very specific cases of motorways, trunk roads and ‘Special Roads’ are an exception to this.)
Ownership, rights of way, and rights of passage are separate issues which don’t determine (and aren’t determined by) the Public or Private Road status.
Have we surpassed concretegate yet?
