No evidence has been found to identify this as a Roman road, in fact there seems no need to climb up and then down when there is a perfectly straight forward route to replace it.
It is most probable that this was a road to the Quarry at the top of the hill. Excavation across the road did not provide any evidence of it being Roman. Also where did this road go to and from? If roman it must have continuations on either side and certainly to the south it is far too steep.
Something is not right. This message is just to keep things from messing up down the road
