Welsh Aquaduct

Updated: Jun 19, 2020

Pontcysyllte Aqueduct and canal in Wales consists of a continuous group of civil engineering features from the heroic phase of transport improvements during the British Industrial Revolution. The canal brought water borne transport from the English lowlands into the rugged terrain of the Welsh uplands, using innovative techniques to cross two major river valleys and the ridge between them.

It was built between 1795 and 1808 by two outstanding figures in the development of civil engineering: Thomas Telford and William Jessop. It is 307 meters long.

Although a structure recognised internationally as a masterpiece of waterways engineering and a pioneering example of iron construction, time has taken its toll on the railings which now need replacing. We have made the boxless set ups and coreboxes so the foundry can manufacture more uprights.

The Pontcysyllte Aqueduct - full name in Welsh: Traphont Ddŵr Pontcysyllte, is a navigable aqueduct that carries the Llangollen Canal over the valley of the River Dee in Wrexham County Borough in north east Wales.

Completed in 1805, it is the longest and highest aqueduct in Great Britain, a Grade I Listed Building and a World Heritage Site. The viaduct carries a water passage for a single canal narrow boat as well as a towpath for pedestrians, and is now a popular tourist excursion; boat trips cross the viaduct and return.
