Included in this batch was the Cannock Extension Canal, to run from Pelsall Junction on the Wyrley and Essington to Hednesford, where there were coal mines.

The land on which the link would be built was purchased jointly by the two companies, but the Staffordshire and Worcestershire Canal seems to have funded the actual construction.

[4] The date when the Hatherton Branch and the Churchbridge locks ceased to be used is given as 1949 by Hadfield[5] and 1953 by Shill, but in either case, the junction closed around this time.

[6] The Cannock Extension Canal was increasingly affected by subsidence from the coal mines it served, and the northern section, including Rumer Hill Junction, closed in 1963.

By the time the 1957/1962 map was published, the tramway had been dismantled, Leacroft Wharf was disused, Washbrook Lane had been destroyed to the south of the canal, and only the top lock of the Churchbridge flight remained.
