Calstock Viaduct
The Calstock viaduct is part of the Tamar Valley railway that was constructed at the start of the 20th Century and still runs between Gunnislake and Plymouth. The viaduct was built between 1904 and 1907 from 11,148 precast concrete blocks. It is 120 feet high with twelve main arches each 60 feet wide, and one mini-arch at the Calstock end. Originally, a steam-powered lift was attached to it which could raise and lower wagons from the quays over 100 feet below.
