Description
The Longdon Aqueduct, built in 1795 and designed by Thomas Telford, is located on the Shrewsbury Canal. It is notable for being one of the first cast iron aqueducts, although the one at Holmes on the Derby Canal was completed just a month earlier. This aqueduct is part of the Shropshire Union Canal and carries the Shrewsbury Branch over the River Tern. It features an iron trough that is square in section, supported by iron uprights with diagonal bracing. There is a tow path along the south side of the trough, which is lined with plain iron railings. At each end, there are sandstone and brick abutments with round arches, and the east abutment includes corner buttresses. These abutments are believed to be remnants of a previous aqueduct that was destroyed by floods early in 1795.
