53°29′37″N 02°02′25″W / 53.49361°N 2.04028°W / 53.49361; -2.04028The Huddersfield Narrow Canal Pylon, (National Grid tower designation 4ZO251B), is a 54.6 metres (179 ft) tall electricity pylon which stands with its feet over the Huddersfield Narrow Canal near Heyrod, Stalybridge, Greater Manchester, United Kingdom.
The Stalybridge substation was built while the canal was closed to navigation, encroaching on the former canal line, and the canal was culverted at this point from the head of Lock 8W to a point immediately downstream of the substation.
The extent of the former culvert can still be seen, as it was reused to form the lock bywash.
When the canal reopened, the channel was diverted slightly to the east to avoid the substation compound.
