The Leaderfoot Viaduct is a railway viaduct over the River Tweed near Melrose in the Scottish Borders. The railway was severely damaged by flooding during August 1948, with 7 bridges on the line failing, and the line closed to passenger traffic on 13 August 1948. Freight trains continued to run across the viaduct as far as Greenlaw until 19 July 1965. Historic Scotland took over control of the viaduct from British Rail in 1996. [Wikipedia].
