The Longdon-on-Tern Aqueduct, near Longdon-on-Tern in Shropshire, was one of the first two canal aqueducts to be built from cast iron.

History

The cast iron canal aqueduct was designed by Thomas Telford and built in 1796 to carry the Shrewsbury Canal across the River Tern near Longdon-on-Tern in Shropshire.[1] The 186 feet (57 m) aqueduct was opened one month after Benjamin Outram's 44 feet (13 m) cast iron Holmes Aqueduct on the Derby Canal, the world's first cast iron canal aqueduct.[2][1] Since the closure of the Shrewsbury Canal in 1944, the aqueduct has been disused.[1] The aqueduct is an Historic England Grade I listed building and has been on the register since 30 March 1971.[2]

Description

The canal was carried in a cast iron trough 9 feet (2.7 m) wide, 3 feet (0.91 m) deep and 186 feet (57 m) long and divided in four spans, each of 47 feet 8 inches (14.53 m).[1]
