The Swing Bridge and the High Level Bridge reflected into the River Tyne.
The Swing Bridge is a located over the River Tyne, connecting Newcastle and Gateshead, and lying between the Tyne Bridge and the High Level Bridge (Shown in the background). The Swing Bridge is a grade II listed structure.
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.
It has an 281 ft (85.6 m) cantilevered span with a central axis of rotation able to move through 360° to allow vessels to pass on either side of it.
The busiest year of operation was 1924 when the bridge was rotated 6,000 times unlike current use where it is only required to turn occasionally to allow yachts and pleasure craft to pass by and on the first Wednesday of each month as a maintenance exercise.
