River Cart Aqueduct
History
The aqueduct was built between 1808 and 1810, and opened in 1811 to carry the Glasgow, Paisley and Johnstone Canal. John Rennie and Thomas Telford were involved in the engineering process. The contractor was John Simpson and the cost of construction was £5,440.
The canal was closed in 1881, and converted to run the Paisley Canal Line, which opened in 1885.
Design
It is a freestone masonry segmental arch of 88 feet 6 inches (27 m) span and a height over the water of about 30 feet (9 m). The bridge is probably the longest span masonry aqueduct of the canal age on a British canal, and one of the world's earliest bridges carrying a public railway. It was widened to carry the double track railway, and the line crosses the bridge at a slight skew because of the easing of the sharp canal curvature.
When the aqueduct carried the canal, it was only the width of a single boat, making it necessary to wait for another boat to pass at times.
