Cambrian Wharf in Birmingham city centre used to be a junction of the Birmingham and Fazeley Canal (Farmer's Bridge Junction) and the Newhall Branch of the Birmingham Canal Navigations.
When most of the branch was closed post-war (and later city development built on top of it) the junction was turned into a basin and residential moorings. The canal stretch from Cambrian Wharf to Old Turn Junction is all that remains of the Newhall Branch (though is just included as part of the Birmingham and Fazeley these days).
