Northern 4 Span Aqueduct, Duchray Valley

The Northern 4 Span Aqueduct in the Duchray Valley was constructed between 1856 and 1859 by engineer John F Bateman, with ironwork by Alston & Gourlay. Some alterations were made between 1860 and 1864. This 154-yard aqueduct bridge features an iron trough supported by three battered piers and steep battered masonry embankments at both ends. The outer piers are made of masonry, while the central pier is constructed of concrete and includes an access door at its base. The cast-iron trough connects to embankment sections, with riveted wrought-iron used in the center. The piers are made of coursed, bull-faced sandstone, and the embankments consist of whinstone rubble. The embankments are capped with sandstone ashlar. At each end, the conduit emerges from a sandstone archway, and standard Glasgow City Water Works plain cast-iron railings are present. In 2007, a security cover and railings were added to the embankment sections of the trough.
