The swing bridge was built in the 1930s by Sir William Arrol. It

During 2000 and 2001, the bridge was refurbished and
new mechanical, hydraulic and electrical systems fitted to make
it fully operational again, allowing canal traffic
The bridge carries a single carriageway road (with external
cantilevered footpaths on both sides) over the Forth and Clyde
canal and has a nose span of approximately 13.2m and a tail span of
In order to refurbish the bridge it was necessary to remove the
main pintle bearing for inspection and refurbishment. This
involved raising the bridge (weighing 300t) approximately 1000mm
vertically to allow the bearing to clear the main bridge beams. The
bridge was raised over a period of 24 hours prior to removing the
pintle. Once the pintle was removed the bridge was lowered
back down to road level onto timber hardwood and steel packing
bearers. This enabled the bridge to be re-opened to road
traffic whilst the pintle was refurbished and other contracted
A further technical aspect of the works was the redesign of the
road junction and associated traffic light system. The bridge
operates on a simple control panel whereby the bridge operator
merely presses a button to commence the opening sequence.
The contract is complete. Other minor works to the bridge
included the repainting of the bridge superstructure and
refurbishment of the control housing.
The work was completed between September 2000 and March 2001.
The contract was valued at approximately £650,000
