As Waggy says, the main works are on the track in the bottom of the dale to prevent bikes and vehicles going up onto the spoilheaps of the opencuts - there are no changes to the status of the road, which I think is a BOAT. I can't remember whether there were any plans for works to prevent vehicles getting shoved into the opencuts from the top.
Follow the horses, Johnny my laddie, follow the horses canny lad-oh!
