Carnon viaduct, Railway viaduct in Perranwell, Cornwall, United Kingdom.
The Carnon viaduct spans 756 feet across the Carnon River valley, featuring nine masonry arches that support the Maritime Line between Truro and Falmouth.
In 1863, engineer Isambard Kingdom Brunel designed the original timber structure, which was replaced by the current stone viaduct in 1933 at a cost of £40,000.
The viaduct stands as a representation of Cornwall's industrial heritage, connecting communities through the railway network that transformed local transportation.
The structure remains operational on the Truro-Falmouth railway line, with trains passing regularly over its 96-foot-high spans while offering views of Restronguet Creek.
The construction required innovative engineering solutions, using cast iron caissons sunk to bedrock through mudflats to establish stable foundations in challenging terrain.
