Shillamill Viaduct

Shillamill Viaduct is a railway viaduct built in 1889 by the Plymouth, Devonport and South Western Junction Railway, with engineers Galbraith and Church and J.W. Szlumper for the London and South Western Railway. The structure is made of squared rock-faced granite, featuring ashlar quoins, dressings, and arch-rings. It is a double-track viaduct with twelve 50-foot arches arranged almost in a straight line, measuring about 700 feet in length and reaching a height of approximately 100 feet. The piers taper from a plinth to a cornice and support semi-circular arches. The parapet includes a band and a canopy, with a slightly projecting refuge above every second pier. The viaduct also carries a tablet marked R+P 1889, indicating the builders Relf and Pethick.

Historically, this viaduct was part of the extension from Exeter to Plymouth, providing the London and South Western Railway with a fully controlled route between London and Plymouth. The section from Lydford to Devonport was the last to be completed, opening in 1890. The line was closed and lifted west and south of Lydford in 1968, and is currently only operational from Bere Alston to Plymouth.
