During the Industrial Revolution of the 18th century, navigable aqueducts were constructed as part of the boom in canal-building. A notable revolving aqueduct has been made on the Bridgewater Canal . This allowed vessels to cross at high and low levels while conserving water that would be lost in

A modern version of an aqueduct is a pipeline bridge . They may take
40-400: The aqueducts were lower than the upper part of the waterway by 6 metres (20 ft), a reversed siphon mechanism works when water flows through the aqueducts. The stone aqueducts were made watertight with mortar. The bridge was completed in 1854.

After that, the wooden frames were removed. Because
