Llandinam Bridge

Llandinam Bridge stands in the village of Llandinam in Powys, Wales. It crosses the River Severn near the main A470 road and its byroad. The bridge is made of cast iron and has a single segmental arch. This arch is 27.4 metres long and rises by 2.7 metres. Three curved cast-iron ribs support the bridge, each 685 millimetres deep and 63 millimetres wide. The bridge was designed by Thomas Penson and built in 1846. It replaced an earlier timber bridge that had stood on the same site. The ironwork was cast by the Hawarden Ironworks in Flintshire. The design follows principles used by Thomas Telford for bridges in Craigellachie. In 1906, vehicles over three tonnes were banned from using the bridge. A statue of industrialist David Davies stands at the east end of the bridge. The bridge’s spandrels have an X-shaped pattern, stiffened by cruciform and circular cross-members. The surface is flat and falls towards the west, with horizontal girders running along both sides. The abutments are built of ashlar masonry sloped at 30 degrees.
