Description
The Avon Aqueduct, part of the Edinburgh and Glasgow Union Canal, was engineered by Hugh Baird and constructed in 1822. Built with the input of both Baird and Telford, it is a substantial structure, 810 feet long and 86 feet high. The aqueduct comprises 12 round arches built from cream-coloured, squared and stugged sandstone rubble and bull-faced rubble. A cast-iron railing now runs along the parapet, replacing an earlier wrought-iron one. A cobbled towpath runs along the top and a cast-iron trough carries the canal water. The aqueduct is a Scheduled Monument.
