Penadlake Viaduct

Penadlake Viaduct is a railway viaduct built in 1877 to replace Isambard Kingdom Brunel's earlier tresselled timber viaduct that opened in 1859. The structure features seven tapering piers made of massive snecked rock-faced slatestone, with a clear span of approximately 40 feet. It carries eight semicircular arches, which are constructed with dressed rusticated granite voussoirs and quoins. The parapet has been partly rebuilt and includes rusticated stone coping with simple refuges. The viaduct is slightly curved in plan and is part of a series of viaducts built in quick succession along Brunel's Plymouth to Truro Cornwall Railway broad gauge line. The railway line itself was opened in 1859.
