Description
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.
Local climate
Derricombe Viaduct sits in a wetter-than-average part of the UK, with an average of 1,030 mm of rain a year. This makes it wetter than 82% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 87% of listed buildings.
It experiences an average of 16 freeze-thaw cycles a year, fewer than 84% of listed buildings. Of these, 7 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.
Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
