Clinnick Viaduct

Clinnick Viaduct is a railway viaduct built in 1879, with earlier piers constructed in 1859 by Isambard Kingdom Brunel. The structure features six tapering piers made of snecked rock-faced slatestone, each with an approximate clear span of 30 feet. These piers support six semi-circular arches made with granite long and short voussoirs, and include centreing holes and rock-faced slatestone above. A moulded corbel course with bonding stones rests on moulded stone brackets, which support an iron parapet railing featuring uprights, lattice braces, and ornamented adjustment rings. There are two contemporary refuges that project out from carved granite ball bases. Located two meters north are the 1859 abutments and two tapering piers made of smaller, roughly squared stone, one of which is covered in ivy. These piers are bone-shaped in plan, approximately 50 feet high, and have a clear span of about 40 feet. The viaduct formerly supported two or four raking timber trestles. Clinnick Viaduct is part of a series of viaducts along Brunel's Plymouth to Truro Cornwall Railway broad gauge line, which originally opened in 1859.
