Cubes

Part of the mechanism of the lift bridge over the entrance to Surrey Water in Rotherhithe Street.

As the big red 'wheel' rolled back towards where the camera is sited it was guided by the pegs going into the holes on the rim and the road deck, which was attached to the wheel, was thus raised so that ships could pass through I believe it was driven by high pressure water.
