Introduction
The photograph on this page of Lifting canal bridge by David Neill as part of the Geograph project.
The Geograph project started in 2005 with the aim of publishing, organising and preserving representative images for every square kilometre of Great Britain, Ireland and the Isle of Man.
There are currently over 7.5m images from over 14,400 individuals and you can help contribute to the project by visiting https://www.geograph.org.uk

Hydraulic lifting bridge on the B816 over the Forth and Clyde canal at Bonnybridge. For many years, the canal was unnavigable at this point as there was minimal clearance for vessels. When the canal was reopened, a hydraulic bridge which raised the roadway to allow passage was installed. The lifting is done by four columns, one in each corner. Similar bridges exist at Twechar and Grangemouth. However the mechanism fell into disrepair and the bridge became non-operational (the same at Twechar) meaning that coast to coast navigation was again impossible. The mechanisms were repaired in 2019, before the canal festival, when this picture was taken.
