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.
