The Pontcysyllte Aqueduct (Welsh pronunciation: [ˌpɔntkəˈsəɬtɛ]; Welsh: Traphont Ddŵr Pontcysyllte) is a navigable aqueduct that carries the Llangollen Canal across the River Dee in the Vale of Llangollen in northeast Wales.
It lies 200 m west of Thomas Telford's Pontcysyllte Aqueduct and, carrying the B5434 road, is the main connection between Trevor and nearby Froncysyllte. The sandstone bridge is dated '1697', though it was substantially rebuilt during the 18th century, and only the south arch and part of the south pier are original. [4]
A notable feature of the canal is the Pontcysyllte Aqueduct, built by Thomas Telford. Opened in 1805, the aqueduct is more than 300 metres (980 ft) long and 38 metres (125 ft) above the valley floor. It has 19 stone arches, each with a 45-foot (14 metre) span.

The aqueduct was built to carry the Ellesmere Canal over the Dee Valley. Completed during the Industrial Revolution and designed by Scottish Engineer Thomas Telford, the aqueduct made innovative use of cast and wrought iron, influencing civil engineering across the world. [17] [18] The heritage site extends into Shropshire in England. [19]
On the main line section, the Chirk Aqueduct was opened in 1801, and Pontcysyllte Aqueduct in 1805. However, by this time the proposed line from the Dee at Chester to Ruabon had been abandoned as uneconomic. The canal was therefore terminated at Trevor Basin, 2 miles (3 km) southwest of Ruabon.
Out-of-use cast-iron Longdon-on-Tern Aqueduct. Benjamin Outram's 44 ft long (13 m) single-span Holmes Aqueduct on the Derby Canal in Derby was the world's first navigable cast iron aqueduct, narrowly pre-dating Thomas Telford's 186 ft long (57 m) Longdon-on-Tern Aqueduct on the Shrewsbury Canal, sometimes described as the world's first large-scale navigable cast iron aqueduct.
