That's very interesting Jerry, thanks. I thought the byway's reference was a bit odd actually as in it's the same as the byway that it intersects. In my experience, usually the paths I've looked at are a single line ie. a single beginning and end so maybe it has been "tacked on" to an existing path rather than given a new reference.
