Bridge in a puddle

My daughter went to Sheffield today to have a look at the university so I decided to accompany her as far as London. I walked the nine miles of the Regent's canal from Mile End lock west to the Paddington basin. Its quite nice that you can walk so far through London and yet see very few people other than a few joggers and the occasional barge. I can't remember exactly where this was , somewhere past Camden Lock in the section that goes through Regent's Park and London Zoo I think.
