Contraflow access to South Quay

South Quay can currently only be reached legally from King Street by a series of agility challenge actions: over the rough cobbles by the Customs House, then up onto the quay by the flood gate, then along the quay, taking care not to hit the ornamental chains, then a tight turn onto the boom.

The more obvious route through King Staithe Square is blocked by no-entry signs by Purfleet Bridge and at the flood barrier - and that is the direction that the cycle route currently sign points!

There are several ways this could be changed and I wouldn't mind which was done.
