The Loch nan Uamh Viaduct is a railway viaduct that carries the West Highland Line.
The West Highland Railway was built to Fort William by Lucas and Aird, but there were delays with the West Highland Railway Mallaig Extension (Guarantee) bill for the Mallaig Extension Railway in the House of Commons as the Tory and Liberal parties fought over the issue of subsidies for public transport. This Act did pass in 1896, by which time Lucas & Aird (and their workers) had moved south. New contractors were needed and Robert McAlpine & Sons were taken on with Simpson & Wilson as engineers. Robert McAlpine & Sons was headed by Robert McAlpine, nicknamed "Concrete Bob" for his innovative use of mass concrete. Concrete was used due to the difficulty of working the hard schist in the area. McAlpine's son Robert, then aged 28, took charge of construction, with his younger son Malcolm appointed as assistant.
In 1987 Roland Paxton, from Heriot-Watt University, investigated the legend that a horse had fallen into a pier during construction of Glenfinnan Viaduct in 1898 or 1899. However, after inserting a fisheye camera into boreholes made into the only two piers large enough to accommodate a horse, no animal remains were found. In 1997, on the basis of local hearsay, Paxton investigated Loch nan Uamh viaduct using the same method but found only rubble as well. In 2001, he returned to Loch nan Uamh with radar equipment and found the remains of a horse and cart within the viaduct's central pylon.
