Chesterfield Canal Bridge 37 and Turnerwood Lock with Associated Overflow Structure at Cinder Hill

Bridge 37 and Turnerwood Lock, along with an associated overflow structure, are located at Cinder Hill on the Chesterfield Canal. The bridge dates from the late 18th century, while the bridge itself is likely from the early 19th century. It was constructed for the Chesterfield Canal Company.

The bridge features a single span with an integral lock to the west and an overflow channel that emerges at a sluice near the southeast corner. The bridge has round-nosed brick voussoirs forming a basket arch, with abutment walls that curve out to finish at rounded projecting end piers. The parapet, which has stone copings, curves down on either side. An overflow tunnel, also brick-arched, emerges near the southeast corner and discharges into the canal through a lined sluice.

The lock has stone walls at both the entry and exit, with a stone course at low water level and brickwork above. The lock-gate recesses are made of ashlar, featuring hollow-quoined heel-post housings. This structure is an important part of the Chesterfield Canal, which was surveyed by James Brindley and built between 1771 and 1777, remaining in water through the parishes of Thorpe Salvin and North and South Anston. It marks the eastern end of the Turnerwood Flight of locks.
