Swing Bridge in testing for the Lost & Found event which is part of the upcoming Bridges Festival. The bridge was opened in 1876.
The hydraulic power to move the bridge is derived from electrically driven pumps. This feeds a hydraulic accumulator sunk into a 60 foot 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.
