A B-listed railway bridge which crosses the River Tweed at Galafoot, between Langlee and Tweedbank, in the Scottish Borders, the Redbridge Viaduct (occasionally known as the Tweed Viaduct) opened in 1849 to carry the Edinburgh to Hawick Railway, which later became known as the Waverley Line. The viaduct comprises five arches, is constructed in red sandstone and is 85m (278 feet) in length.
The railway closed in 1969 and the viaduct became a popular pedestrian crossing, which later served as part of the Southern Upland Way. The bridge was subsequently refurbished 2014-15 by Network Rail to carry the new Borders Railway, which followed the route of the old Waverley Line. A footpath was retained alongside the re-opened railway.
