The Kelvin Aqueduct is a navigable aqueduct in Glasgow, Scotland, which carries the Forth and Clyde Canal over the River Kelvin.
When opened in 1790 it was Britain's largest aqueduct, and onlookers were impressed at the sight of sailing boats crossing above them. The entire project cost £8,509, exceeding the original estimated cost of £6,200.
It was protected as a category A listed building in 1989.
The piers are buttressed in such a way as to resemble , but only one pier sits in the river. The sides of the aqueduct are arched in order to transfer the outward pressure of the water onto the buttresses, an effect which can clearly be seen from above. This design feature is also present on the Luggie Aqueduct at Kirkintilloch, which opened in 1773.
The aqueduct is built from rustic masonry at the lower levels and polished ashlar above. Underneath it is the Kelvin Walkway, which runs through an area of green space around the river.
Design
It is long, with four arches of span, and high above the surface of the river. According to measurements by John Rennie as the canal was nearing completion, there was around of puddle clay at the bottom of the canal. The aqueduct was designed to carry a depth of of water.
