Avoncliff Aqueduct (grid reference ST803599) carries the Kennet and Avon Canal over the River Avon and the Bath to Westbury railway, at Avoncliff in Wiltshire, England, about 1+1⁄2 miles (2.4 km) west of Bradford-on-Avon. It was built by John Rennie and chief engineer John Thomas, between 1797 and 1801. It is a Grade II* listed structure. During construction, stone from a local quarry was used which split when affected by frost. This caused buttresses to collapse and parts of the structure to need rebuilding. Eventually Bath stone from Bathampton Down was used to ensure greater stability.

| - Avoncliff Aqueduct (grid reference ST803599) carries the Kennet and Avon Canal over the River Avon and the Bath to Westbury railway, at Avoncliff in Wiltshire, England, about 1+1⁄2 miles (2.4 km) west of Bradford-on-Avon. It was built by John Rennie and chief engineer John Thomas, between 1797 and 1801. It is a Grade II* listed structure. During construction, stone from a local quarry was used which split when affected by frost. This caused buttresses to collapse and parts of the structure to need rebuilding. Eventually Bath stone from Bathampton Down was used to ensure greater stability. The aqueduct has three arches and is 110 yards (100.6 m) long, with a central elliptical arch of 60 ft (18.3 m) span, and two semicircular side arches each 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. As part of the 20th-century restoration of the canal, the aqueduct was lined with a concrete "cradle" and made watertight in 1980. (en)

Il a été conçu par les ingénieurs John Rennie et John Thomas, et construit entre 1797 et 1801. Le pont-canal est composé de trois arches et fait 100 m (110 yards) de long, avec une arche elliptique centrale d'une portée de 18,3 m (60 pieds) et deux arches latérales semi-circulaires de 10,4 m (34 pieds) de portée, toutes construites avec des pierres taillées en V. Les écoinçons des arches et les faces extérieures des piles et des culées sont parées d'une alternance d'assises de pierres lisses et de pierres à bossage La travée centrale s'est affaissée peu de temps après sa construction et a été réparée plusieurs fois. Dans le cadre de la restauration du canal, le pont-canal a été doublé d'un « berceau » de béton et étanché en 1980. (fr)
