Architecture, archaeology and continuing use
Five sandstone arches spring in low elliptical curves between piers with rounded cutwaters. Engaged Doric columns, a continuous frieze, pedestrian refuges and a blind balustrade turn structural components into a disciplined classical composition.
Its story
A destructive flood removed Kelso’s earlier bridge in 1797. John Rennie designed its replacement with shallow arches and a level carriageway; completed in 1803, it became an important model for later bridges, including Rennie’s London Bridge.
Why it is included
Category A engineering, intact classical detailing and continuous transport use make the bridge indispensable to both the townscape and the history of bridge design.
What to notice
- Five low elliptical arches.
- Doric columns above the rounded cutwaters.
- Pedestrian refuges and blind parapet balustrade.
Reading the surroundings
This is a busy working road bridge. Use designated pavements, remain alert to traffic and cyclists, do not climb parapets or descend to unsafe river margins, and keep stopping time brief where the footway narrows.
Timeline

- 2026 The bridge remains part of Kelso’s active public road network.
What we know — and what remains uncertain
Traffic management, maintenance and riverside conditions can change rapidly; the record does not imply safe access below the deck.
