Architecture and continuing use
Segmental arches spring between rounded cutwaters that continue upward as buttresses. Ashlar voussoirs run diagonally into the spandrels, giving the masonry a distinctive pattern. Iron cantilevers added width at the sides, and the present balustrade belongs to a later repair campaign.
Its story
John Brown of Dumbarton built the bridge in 1765 after much earlier proposals to cross the Leven. One pier failed soon after completion and brought down two arches; repairs were finished by 1768. W. R. Copeland widened the crossing with iron cantilevers in 1884. Further ironwork repairs and a concrete balustrade followed in 1933–34.
Why it is included
The crossing records the town’s evolving movement needs in one structure and makes repair, failure and widening part of its architectural history.
What to notice
- Diagonal arch stones extending into the spandrels.
- Rounded cutwaters rising as full-height buttresses.
- The difference between the masonry core and iron widening.
Reading the surroundings
Use pavements and crossings and remain alert to traffic. Do not climb parapets or descend onto riverbanks without a lawful maintained route.
