Thomas Telford's Aqueducts on the Shropshire Union Canal

Thomas Telford's five great aqueducts on the Shropshire Union Canal justify his reputation as one of the finest civil engineers. At Pontcysyllte in North Wales he built the highest iron-trough aqueduct in the world, now a World Heritage Site and still in use with narrow boats floating high above the Dee valley. At Chirk, Longdon on Tern, Nantwich and Stretton he built others which are prized for their originality and attractive design.
