Calder and Hebble Navigation

The Calder and Hebble Navigation is a canal system in West Yorkshire, England. Construction was started in 1757 by the engineer John Smeaton to provide a navigable waterway between Wakefield and Halifax. The River Calder was to be used where possible, and canals were cut between sections of the river to straighten it out. The River Hebble[?] was also used. Construction finished in 1770. The Navigation runs from Wakefield via Horbury[?], Ossett, Dewsbury, to Mirfield where it is joined by the River Colne[?] and the Huddersfield Broad Canal[?]. The Kirklees Cut[?] straightens out the river as it continues to Brighouse, then Halifax and Sowerby Bridge. The river continues, but the Navigation terminates where the Rochdale Canal[?] starts.
