Chesterfield Canal, Killamarsh
According to footpath signboards, the water course under the bridge just north of Upperthorpe & Killamarsh was the Chesterfield Canal. West of the bridge the canal is infilled, but starting under the bridge and heading east for a few hundred yards it has been cleared out and is "in water" as I believe they say, albeit very silted up and overgrown with rushes etc.
Regrettably it then disappears north-eastwards under the barrack-like housing which is rapidly taking over the area and also encroaching on the railway remains, see the contruction hoardings at
The towpath is still open as a footpath even on the infilled section, and seemed to be well used by local people. The path is called Cuckoo Dyke. According to the Chesterfield Canal Trust this was the local name for the canal, which ran from Chesterfield to Retford, Gainsborough and the Trent.
A few hundred yards south, beyond the infilled bridge and some fishing ponds in old workings, the canal (with water) re-appears and on Multimap it can be followed for perhaps a further half a mile towards Chesterfield before its course becomes unclear again.
