Is this correct, for NCN 552?
It is a very different route to that shown on the Sustrans map.

Is this not part of cycle route 552, rather than 551? It is bookended by the 552, whereas the rest of the 551 runs from Silverdale to Newcastle-under-Lyme.

The defined continuation of the right of way to Scot Hay Road goes through furnace pool! It seems sensible to update tags to show the commonly used course if a survey shows this to be way marked.

There is a public footpath here (and it is indicated by sign posts at both ends). The line shown is visible on the ground, but is obstructed by low fences. The visible line corresponds with that shown on old maps.

Newer maps show the path going through the sewage works and at the side of the access road. There is no evidence for such a line and access is prevented by high fences.
