Martholme Viaduct

Martholme Viaduct is a 19th-century railway viaduct in the English county of Lancashire. It lies between the town of Great Harwood and the village of Read, and lies in both the district of Hyndburn and that of Ribble Valley. The viaduct was constructed 1870–77 by engineer Sturges Meek. It was built to carry the Great Harwood Loop of the East Lancashire Line over the River Calder. That part of the line closed in 1957.The viaduct was originally intended to be a wooden construction, but was eventually built of sandstone rubble. It has ten round arches, each 40 feet wide. On a slight curve, the viaduct is 65 feet high. In 1984 it was designated as a Grade II listed structure by the organisation then-known as English Heritage.
