The entrance to Dock Street should be turned into a continuous footway with pedestrian and cyclist priority over turning vehicles akin to this Danish junction: http://www.youtube.com/watch?v=QcnmLU1ClTo

This would improve sight lines for pedestrians too as the dropped kerbs are away from the junction, and it would also go with the pedestrian desire line as many tend to cross closer to the junction than the dropped kerbs. It would also slow down the vehicles entering the narrow street.
