Charlie_Towlson: I must admit I haven't checked this one for a while as after providing a replacement I was fairly sure it would still be there. I was wrong. I know this because the cache is no longer there. I know that because the sign it was on is no longer there. I know that because the whole dang bridge alluded to in the desc has gone! Which kinda puts a crimp on things.
The whole roundabout appears to be being used as a base, with temporary(?) structures and heavy equipment in a solid mass. Given that this is unlikely to change in the near future I'm archiving this cache, hopefully at some point in the future it might return in a different guise. My apologies to the last two cachers.
