Architecture, archaeology and continuing use
Five graduated segmental arches extend for roughly 350 feet, with the widest span at the centre. Rock-faced granite contrasts with polished soffits and parapet surfaces, while rounded cutwaters and splayed abutments emphasise the bridge’s controlled flow.
Its story
Rennie designed the bridge late in his career, and it was completed in 1821 to improve the principal valley crossing. Its combination of hydraulic confidence and restrained masonry has kept it both useful and architecturally admired.
Why it is included
Category A engineering, major authorship and uninterrupted transport use make Ken Bridge the strongest infrastructure record for New Galloway.
What to notice
- Five arches increasing toward the centre.
- Rounded cutwaters rising from the river bed.
- Long, low curve of the parapet across the floodplain.
