Loch Nan Uamh Viaduct, Railway viaduct in Highland, Scotland
Loch Nan Uamh Viaduct is a concrete railway bridge that carries trains across Gleann Mama valley with eight wide arches and passes above the A830 road. The structure is built on strong concrete pillars that support the entire weight of the crossing.
The viaduct opened in 1901 as part of the West Highland Extension Railway, linking Fort William to Mallaig through the Scottish Highlands. This railway line brought vital transport connections to one of Scotland's most remote regions.
The structure stands near Loch nan Uamh, where Prince Charles Edward Stuart departed Scotland in 1746 after the Jacobite uprising.
The viaduct remains in active use today, with trains passing regularly on the West Highland Line, making it a working structure rather than a historical relic. Visitors can view and photograph it from the A830 road or from nearby walking paths in the valley.
A horse-drawn cart fell into one of the central pillars during construction and its remains are still trapped inside today. Radar scanning in 2001 confirmed this discovery, making the viaduct an unintended repository of industrial-age mishap.
