Derricombe Viaduct

Derricombe Viaduct is a railway viaduct built in 1881, with three earlier piers constructed in 1859 by Isambard Kingdom Brunel. The structure features four tapering piers that have a clear span of approximately 55 feet, made from massive rock-faced slatestone, which is arranged in courses with dressed slatestone voussoirs and soffits. The parapet is made of smaller slatestone, also brought to course, and includes one refuge with a single bar over the center pier.

To the north, there are three tapering piers from 1859, made of smaller uncoursed roughly squared stones. The central pier is I-shaped in plan and is supported by buttresses with dressed weatherings in two stages. The viaduct formerly carried four raking timber trestles, also with a clear span of about 55 feet. This viaduct is part of a series of viaducts built in quick succession along Brunel's Plymouth to Truro Cornwall Railway broad gauge line, which originally opened in 1859.
