It is a brick structure, with nineteen arches, nearly 100 feet high standing on slender piers. (1,2) Railway Viaduct. It is only justice that the viaduct should be so impressive for the railway made Folkestone. 19 brick arches monumentally spanning the Foord Valley, nearly 100 feet high in the centre.
