context_page_description: William Hazledine was an English ironmaster. Establishing large foundries, he was a pioneer in casting structural ironwork, most notably for canal aqueducts and early suspension bridges. Many of these projects were collaborations with Thomas Telford, including the Pontcysyllte Aqueduct and the Menai Suspension Bridge.
  Telford called him "the Arch conjuror himself, Merlin Hazledine".
context_section_description: In the following years Hazledine supplied ironwork for many projects of Thomas Telford.
  He made the iron deck for the Chirk Aqueduct, completed in 1802. He built a large foundry at Plas Kynaston, Cefn Mawr, where he made the iron deck for the nearby Pontcysyllte Aqueduct, completed in 1805.
  The Bonar Bridge in Scotland, an innovative design by Telford with a central span of 150 feet (46 m), was built in 1811–12;  The ironwork was cast at Plas Kynaston, and Hazledine supervised its erection. There were several more bridges of this design, including the Mythe Bridge, with a span of 170 feet (52 m), at Tewkesbury (1823–26).
  From about 1815 to 1820 he supplied and fitted lock gates for the western half of Telford's Caledonian Canal.
  In 1821 Hazledine contracted to supply the wrought iron and cast iron for the Menai Suspension Bridge. The bridge, designed by Telford, was completed in 1826. He also supplied the ironwork for Telford's Conwy Suspension Bridge, completed the same year. The tensile strength of the wrought iron chains, made at Upton Forge, was important to these suspension bridges.
