Rather than let the Macclesfield Canal join directly, the Trent and Mersey canal company built a short 1.5 mile branch. To stop water being lost to either canal two stop locks were built back to back, so that the higher level one would be used to pass boats. Now only the Macc one survives leaving just the recesses for the gates in the other lock. This is because the levels in either canal could be higher than the other because the summit level of the Trent and Mersey canal was used to store water when it could. We also see the two aqueducts (one road and one the main line canal) and junction with the Trent and Mersey canal at Hardings Deep Junction, and the Northern portals of the old (right hand side) and new Harecastle tunnels.
