Bridgewater Canal Halfacre Lane Aqueduct

The Halfacre Lane Aqueduct, built around 1770 by James Brindley, is an aqueduct located over the Bridgewater Canal in Grappenhall. Constructed of red sandstone and red-brown brick, it features a segmental arch primarily made of brick that curves downward towards the center. Each end of the archway shows a small section that indicates a slightly later extension. The side walls beneath the arch have a curved batter and a plinth in the central portion. The stone abutments are also curved and battered, featuring keystones and plain stone bands that back the brick voussoirs. On the south side, there is a plain stone cap, while the corresponding band on the north side supports a plain brick parapet for the towpath.
