Architecture, archaeology and continuing use
Segmental arches spring from battered piers with cutwaters. Grey ashlar, rusticated voussoirs, bull-faced outer work and slightly splayed parapets give the level roadway a robust finish.
Its story
Murdoch and Weir completed the bridge in 1855, marking the date on the parapet ends. It remains part of the local road and path network beside Blackaddie.
Why it is included
The bridge is a strong, still-functioning example of local mid-nineteenth-century civil engineering.
What to notice
- Three segmental arches across the river.
- Bull-faced piers and channelled voussoirs.
- 1855 date stones at the parapet ends.
Reading the surroundings
Traffic uses the bridge and pavements or verges may be limited. Observe from safe public ground and never stand in the carriageway.
