The Truro viaduct

The longest viaduct in Cornwall is at Truro. It was built of stone in 1904 and is 405 m (1,329 ft) long with sixteen arches and a maximum height of 26 m (86 ft). It was the last replacement of a Brunel viaduct. From the train, it provides a magnificent view of the city. Alongside it, fourteen of the original Brunel piers are still standing.
