History

One of a group of ‘fish-bellied’ iron bridges probably designed and constructed by George Buck, engineer of the Montgomeryshire Canal. He was engineer of the Western branch in 1832-3, but bridges of this type were built up to c1850.

Exterior

Cast-iron ‘fish-bellied’ beam bridge. There are 5 original beams supporting a renewed deck with plywood soffit. The parapets consist of timber posts and 3 rows of modern steel rails. The iron beams sit on splayed brick abutments with sandstone copings and padstones. Immediately to the S are cast iron rebates for stop planks, and a sandstone block with iron ring no doubt for attaching boats. Beyond is a weir with wooden planks, leading down to the W.

Reasons for Listing

Listed as one of a small group of ‘fish-bellied’ iron bridges over the Montgomeryshire Canal. These bridges represent the early use of girders of this characteristic shape, designed to compensate for the low tensile strength of cast iron.
