From Autherley Junction to the Manchester Ship Canal
There are two branches, the Middlewich Branch (which runs from Barbridge Junction to the Trent & Mersey Canal at Middlewich) and the River Dee Branch (which runs from the main line at Chester to the tidal river Dee).
There is also a Newport Branch that is derelict, but under restoration as part of the Shewsbury and Newport Canal that joins at Norbury Junction.
The Shropshire Union Canal was formed from a group of canal companies, which became the Shropshire Union Railways and Canal Company in 1846.
IWA has proposed improved links between the Shropshire Union Canal and the river Dee.
