Notice the two bungalows below Shireoaks bridge – they apparently flooded, or at least got a little damp, when the canal was reinstated – which is why Boundary lock was required. Through the trees on the non-towpath side is a cricket ground and a private fishing lake.
Boundary lock was new in 1998.
The bridge crosses to a footpath leading to Cinderhill and back to Shireoaks Church around the fishing lake.
Immediately after Boundary lock is the Ryton aqueduct. This marks the Nottinghamshire / South Yorkshire boundary.(That’s why they called it Boundary Lock!)
Duke’s Bridge is about fifty yards past the aqueduct
