The Treffry Viaduct is a historic dual-purpose railway viaduct and aqueduct located close to the village of Luxulyan, Cornwall, England in the United Kingdom. The viaduct crosses the Luxulyan Valley, and with it forms an integral part of the Cornwall and West Devon Mining Landscape, a World Heritage Site.
In 1813, Joseph Austen inherited the estates of the Treffry family on the death of his mother's brother (he changed his name to Treffry in 1838). He began to develop the assets, particularly the mineral wealth, and saw that the Luxulyan Valley was a convenient route between the south coast and the high ground in mid Cornwall. He built a new artificial harbour, completed in 1829, at Par, a canal up the valley to Ponts Mill and an inclined plane railway to the Fowey Consols mine on Penpillick Hill. To bring water power to the mine he built a leat from Luxulyan along the west side of the valley. He also acquired the moribund port of Newquay and land and mines in the area of Goss Moor, and planned to link them by a railway system.
