Aqueduct Bridge Over River Duchray, Duchray Valley

The Aqueduct Bridge over the River Duchray in the Duchray Valley consists of two adjacent aqueduct bridges that carry siphon pipes across the river. The first bridge, built between 1856 and 1859, features a three-span design with a central segmental-arched cast-iron span that has open spandrels over the river, flanked by small round-headed masonry arches on either side. It has slightly battered pilastered piers beside each masonry arch and battered masonry abutments. The bridge is constructed from squared whinstone rubble with red sandstone ashlar dressings, and includes a string course and a projecting cope. There are later railings added around 1880 to the parapet, which feature a flower motif on the top section of the uprights and spiked ball finials on the principal uprights. The carriageway is timber-boarded, and standard Glasgow Corporation Water Works cast-iron gates are located at each end, set between random rubble walls.

The second bridge, built between 1880 and 1881, is a mild steel trussed girder bridge that is supported by tapered masonry piers with battered abutments at both ends. It features coursed, bull-faced red sandstone piers and roughly-coursed whinstone rubble abutments.
