William Edwards (February 1719 – 7 August 1789) was a Welsh Methodist minister who also practised as a stonemason, architect and bridge engineer. Edwards was born the son of Edward David in Eglwysilan, Caerphilly County Borough in a small farmhouse, and began preaching in his early twenties. In 1745, he became joint pastor of a newly established Independent chapel at Groeswen, remaining in the post until his death. He taught himself the rudiments of masonry and at the age of 27 was commissioned to build a bridge over the Taff for £500 and to maintain it for 7 years. After several attempts he succeeded and went on to build further bridges across south Wales. On his death, he was buried in St Ilan's church in Eglwysilan, where his tomb is a grade II* listed structure. Three of his sons (Thomas, David and Edward) also became bridge builders, two of whom built Newport bridge in 1801. A fourth son (William) was killed in action at Gibraltar.

His walls were observed to be so neat that he was everywhere in request. Career In 1746, when it was proposed to throw a bridge over river Taff, he was employed to build it. However, Edwards had not sufficiently provided for the passage of the floods, which in certain seasons rush down from the Brecon Beacons. It proved to be a serious obstruction in the way of a heavy flood which swept down the valley about two years and a half after the bridge had been completed. Trees were torn up by the roots and carried down the stream and dammed the torrent. Force finally swept away arches and piers together, carrying the materials far down the river. Edward's second bridge was a failure because of daring experimentation. His friends generously came forward and helped him with the means of building his third bridge, which proved a complete success. The plan which he adopted, of more equally balancing the work and relieving the severe thrust upon the haunches,
