Pontcysyllte: waterway on a metal aqueduct

In a few sentences

In brief

The engineering ensemble decides how the canal goes through difficult terrain.

Useful to know

The Pontkissilte aqueduct and canal in northeastern Wales were completed in the early 19th century. UNESCO highlights the work of Thomas Telford and the use of cast iron and wrought iron in a monumental metal structure. [1]

It's not just a bridge that accidentally has water on it. Continuous waterway is the main task. In a cross-section, compare the vessel holding the water to the structure beneath it. Thus, it becomes clear why a hydraulic function and a bearing system should be considered together, and not as a separate decoration and a separate bridge.
