Description

Llanellen Bridge is a 3-arch stone bridge built in 1821. It features semicircular arches with keystones and low pointed cutwaters that have pilaster strips above them. The downstream side includes long modern concrete cutwaters and attached pipelines. The parapets are topped with flat ashlar coping that sweeps out into cylindrical piers at each end. In the center of the downstream side parapet, there is an inscribed stone that reads: 'Designed and Builded by John Upton of Gloucester, Engineer 1821 for the County of Monmouth.'
