Dunardry Rolling Bridge

Dunardry Bridge

Dunardry Bridge is a unique example of canal history. It is the only hand-operated rolling bridge in the UK which crosses a lock chamber. 

There are other moveable bridges across lock chambers and other rolling bridges, but Dunardry Bridge is the only example of both.

The bridge was installed in 1900, spanning Lock 11 to replace the existing swing bridge which was thought to be too heavy for its function and operation.

Several campaigns of maintenance and repair works were undertaken at Dunardry Rolling Bridge in the early 2000's, including replacement of rolling track supporting sleepers in 2004 and a series of holding repairs in 2008. 

Current Status

The bridge was temporarily closed to some vehicles in July 2009 and closed to all vehicles in July 2015. The bridge has been out of service since 2015 following its closure for health and safety reasons. 

A report undertaken by AECOM ‘Inspection and Refurbishment Options Report’ in November 2015 outlined five potential options for consideration;

• Option 1 – Do nothing
• Option 2 – Refurbish for pedestrians and cyclists
• Option 3 – Assess and refurbish for limited vehicles
• Option 4 – Assess and refurbish for full highway loading
• Option 5 – Replace with new structure

The report recommended the Option 3 be progressed as it would “allow some vehicle access across the bridge for local residents whilst providing an extended service life and minimising changes to the aesthetics of the structure”. 

Future 

Much has changed since the AECOM report was produced in 2015, not the least of which are the financial challenges faced by public sector organisations like Scottish Canals. Scottish Canals recognises Dunardry Bridge's importance though, not just as an example of Scotland's industrial and canal heritage, but as a means for local people to cross the canal. Scottish Canals' colleagues are currently reviewing and exploring options as to how we can bring Dunardry Rolling Bridge back into action in the most appropriate way. We will engage with local communities and stakeholders as we progress.
