Well paulos66, surely you can see why this question is so confusing for someone unfamiliar with Newcastle? I have been to Newcastle a few times and never knew that there was a tiny section of motorway in the centre. Also, you did not make it clear that the human chain you were on about was going to a different level, it sounded as though there were a load of people linking arms on the central reservation or something! Sorry I don't know the answer to your question but it does explain why when I went to see Liverpool play away at Newcastle in the 80's the police brought all the coaches to the back of the away end and escorted them out of Newcastle, and for people like us who had travelled by car they gave us a lift in a black moira back to our car!
