The Calder and Hebble Navigation is a broad inland waterway, with locks and bridge holes that are suitable for 14-foot-wide (4.3 m) boats, in West Yorkshire, England. Construction to improve the River Calder and the River Hebble began in 1759, and the initial scheme, which included 5.7 miles (9.2 km) of new cuts, was completed in 1770 and has remained navigable since it was opened. Significant improvements were made, including the Salterhebble branch to Halifax, opened in 1828, and ever-longer cuts to bypass river sections. Trade was assisted by the opening of the Rochdale Canal in 1804, which provided a through route from Sowerby Bridge to Manchester. There were plans to abandon the river sections completely in the 1830s, but these were modified as the needs of mill owners and other riparian landowners were recognised.

John Smeaton was a British civil engineer responsible for the design of bridges, canals, harbours and lighthouses. He was also a capable mechanical engineer and an eminent physicist. Smeaton was the first self-proclaimed "civil engineer", and is often regarded as the "father of civil engineering". He pioneered the use of hydraulic lime in concrete, using pebbles and powdered brick as aggregate. Smeaton was associated with the Lunar Society.
