Thornyford Bridge, Blackskull Road, Dromore, Co Down, BT27

Thornyford Bridge is a four-span masonry arch bridge which carries a minor road over the River Lagan. The bridge is constructed with random rubble blackstone throughout. The four arches are of approximately the same size and have semicircular profiles, undressed voussoirs and gunited soffits. There are angled shallow cutwaters at both ends of the piers, rising to arch crown level and tapering off on the parapets. The parapets are coped with roughly squared stone blocks and splay out slightly at both ends. The carriageway has a slight curve and a water pipe is buried therein. Two telegraph poles have been placed across the upstream face of the bridge to stop cattle wading downstream. Setting Rural in farmland; heavily wooded riverbanks. There is a drinking place for cattle on the south bank at the east side of the bridge.
