Railway Viaduct Railway Viaduct Including Redundant Piers, Over River Kenwyn

The railway viaduct over the River Kenwyn in Truro includes redundant piers from the original structure built in 1858, with the present viaduct completed in 1904. The redundant piers, designed by Isambard Kingdom Brunel, are made of dressed granite, while the rest of the viaduct features rock-faced granite with brick arches and a rendered parapet fascia. The structure consists of 11 spans and retains 5 surviving Brunel piers, which are rectangular in shape. The round arches are supported by tapered piers that have corbels for timber centring. There are refuges every 3 bays above the piers, and the Brunel piers are spaced 60 feet apart, originally supporting fan-shaped timber constructions.
