This is a large, very old, and intact example of a swing bridge, located in a unique setting between two high level bridges which are also historic.
According to Wikipedia's citation of an article by the Port of Tyne, "The hydraulic power still used to move the bridge is today derived from electrically driven pumps. These feed a hydraulic accumulator sunk into a 60 ft (18 m) shaft below the bridge; the water is then released under pressure which runs the machinery to turn the bridge. The mechanism used for this is still the same machinery originally installed by Armstrong."
HistoricBridges.org's photo-documentation is extensive for this bridge, yet lacks views from inside the swing pier. A few guest photos provided below offer views inside the swing pier and allow views of the machinery of the bridge.
