Avoncliff

Avoncliff is a small village in west Wiltshire, England, in the north of Westwood parish about southwest of Bradford-on-Avon.

It is the point at which the Kennet and Avon canal crosses the river and railway line via the Avoncliff Aqueduct, which was built by John Rennie and chief engineer John Thomas, between 1797 and 1801. The aqueduct consists of three arches and is 110 yards long with a central elliptical arch of 60 ft (18.3 m) span with two side arches each semicircular and 34 ft (10.4 m) across, all with V-jointed arch stones. The spandrel and wing walls are built in alternate courses of ashlar masonry, and rock-faced blocks. The central span sagged soon after it was built and has been repaired many times.
