Calder and Hebble Navigation (Halifax Branch)

Wikipedia has a page about Calder and Hebble Navigation

The Calder and Hebble Navigation is a broad inland waterway, with locks and bridgeholes 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.

With the coming of the railways, the canal was leased to the Manchester and Leeds Railway in 1843, but this was subsequently deemed to be illegal, and the Aire and Calder Navigation with which the Calder and Hebble Navigation connected at its eastern end, leased the canal from September 1847 until 1885. Some of the locks were enlarged, but many were not, and having been designed for Yorkshire Keels, they remain among the shortest on the English connected waterways network, at 57 feet (17 m). The navigation became a cul-de-sac in the 20th century, but with the burgeoning interest in leisure use of the canals, the trans-Pennine Rochdale Canal was reopened in 1996 and the Huddersfield Narrow Canal followed in 2001, resulting in the navigation becoming part of three Pennine cruising rings.
