The Luggie Aqueduct carries the Forth & Clyde Canal over the Luggie Water at Kirkintilloch,^[1] to the north of Glasgow.^[2] It is a Category A listed building.^[3]

It was built by John Smeaton for the Forth and Clyde Canal between 1768-75.^[4]

The aqueduct is 37.8 metres (124 ft) long with a single arch span of 13.7 metres (45 ft), and 27.4 metres (90 ft) wide, with a full width canal that allows two boats to pass.^[4][5]

In 1848, the Campsie Branch line was constructed, and crossed the canal through the arch of the aqueduct but above the water beneath.^[4] The railway was carried on a twin-arch culvert to carry the water underneath it.^[4] The railway has since been removed, and there is now a footpath beneath the aqueduct but with the lines of the rails still visible.^[3] There is an old black and white picture of a boat crossing the canal, with a train passing underneath the boat, with the Luggie flowing below the train.^[6]

The sides of the aqueduct are arched, with a rise of about 1 in 10, a feature also employed on the Kelvin Aqueduct.^[4][7] The aqueduct and the bridge below are built from grey ashlar.^[3]
