I've dizzied myself around that a few times. Good to see it turned into 'art' for us. The placing of the no right turn sign on the third adds to the sense of confusion. There used to be a bar on the town side of that bridge which had an L shaped snooker table...for added angled shooting fun.
I passed this a couple of weeks back and wondered if there was a shot to be had and it would appear there is.nice one.
