Calstock viaduct. Completed march 1908. Built as part of the plymouth, devonport + south west junction rialway, which had bought the east cornwall mineral railway in 1894. Precast concrete block, manufactured on site in the casting yard on the devon side.12 round arches, with rectangular plan tapered piers, in rusticated blocks with rounded cutwaters. The arches have imposts and voussoirs, plain parapets and coping; stepped corbel between each pair of arches, forming refuges in the parapet. There are similarities between this viaduct and that in poundstock, cornwall. During consturction the blocks and other components were transported across the length of the viaduct by means of blondins, or aerial ropeways. Until 1934, there was a remarkable vertical hoist, which was used to raise the lower tram wagons between river bank level and the viaduct (doe).

Calstock Viaduct. Railway viaduct over the River Tamar. Completed March 1908; built as part of the Plymouth, Devonport and South West Junction Railway, which had bought the East Cornwall Mineral Railway in 1894. Precast concrete block, manufactured on site in the casting yard on the Devon side of the viaduct. The viaduct has twelve round arches, with rectangular plan tapered piers, in rusticated blocks, with rounded cutwaters. The arches have imposts and voussoirs, plain parapet and coping; stepped corbel between each pair of arches, forming refuges in the parapet.

Built by John Charles Lang, a public works contractor of Liskeard, with engineers W.R. Galbraith and Richard Church, as part of the link line from Bere Alston to the East Cornwall Mineral Railway in Calstock. There are similarities between this viaduct and the viaduct in Poundstock, Cornwall (see Poundstock list). During construction, the blocks and other components were transported across the length of the viaduct by means of Blondins, or aerial ropeways. Until 1934, there was a remarkable vertical hoist, which was used to raise the lower tram wagons between river bank level and the viaduct.
