I happened to notice that 192-359, a Whitey on our overlays, is sign posted at both ends as a Bridleway. I know there are a couple of wrongly signed lanes in this area, however on checking the Devon County Council where you can walk ride and cycle website
This route has only really ever been a bridleway but after its construction by Aggregate Industries and before its adoption by DCC it had no status, this was only a period of a few months. I think it has already been removed by John from the latest whitey overlay
