Canal Aqueduct, Leeds and Liverpool Canal

The Canal Aqueduct on the Leeds and Liverpool Canal, built around 1771-1774, carries the canal over a public road. The resident engineer was James Brindley, who was succeeded by John Longbotham around 1771-1772. Constructed for the Leeds and Liverpool Canal Company, the aqueduct features large squared sandstone blocks and some brick, with a coursed sandstone rubble parapet on the south side only. It includes a low semi-circular culvert with plain voussoirs at the portals, which are flanked by raked abutments at right angles. The southeast abutment is made of brick, while the northeast one is concrete, both topped with flat stone copings that extend from a plain cornice. There is a short central parapet with rounded coping. This aqueduct is part of one of the earliest and most ambitious trunk canals in the country.
