Loughor Railway Viaduct

The Loughor railway viaduct carries the West Wales Line across the River Loughor. It is adjacent, and runs parallel to, the Loughor road bridge. The 1880 viaduct was granted Grade II listed building status. Before it was demolished in early 2013, the viaduct was the last remaining timber viaduct designed by Isambard Kingdom Brunel.The Loughor viaduct was constructed to carry the broad gauge South Wales Railway west of Swansea to Carmarthen. It was opened to traffic in 1852. The viaduct was rebuilt several times; modifications made include the removal of its swing bridge and broad gauge tracks, replacement of the timber deck with an iron structure, and additional piles. In 1986, due to structural concerns, the track was singled and speed restrictions were imposed adding to journey times.

In the early 2010s, Network Rail commissioned a new-build replacement. Work by contractor Carillion, took place during March and April 2013.
