Healey Dell Viaduct

The Healey Dell Viaduct is a 19th-century structure built between 1869 and 1870 to carry the Lancashire and Yorkshire extension Railway over the River Spodden. Designed by engineer A. Joy, the viaduct is now no longer in use. It is constructed from snecked rock-faced sandstone and features an iron span over the road. The viaduct is a very high structure that spans a deep gorge and consists of eight semi-circular arches, each with a span of 30 feet. The middle three arches are skewed, showcasing winding masonry. The piers of the viaduct vary in design: those that rise from the banks are massive with a square section and stepped pilastered faces, while the piers that support the skew arches are narrow and rhomboidal, built at an angle to the deck but parallel to the river. All piers feature a corbel table at the springing of the arches.
