The Sankey Canal or Sankey Brook Navigation as it is also
know is to be found in Cheshire joining St Helen’s ( Merseyside) with the
River Mersey.
It was built largely to carry coal from the Lancashire
coal fields to Liverpool to feed the growing chemical industries there.
The first survey was done
by Henry Berry and William Taylor and an application to Parliament
was duly made resulting in the Act of 20th March 1755 which
authorised the project. Work was commenced swiftly and the project was
complete by 1757 including three branches to local collieries.
In 1797 an experimental steam powered boat was tried on
the canal carrying a cargo of copper ore, which successfully completed its
10 mile journey along the canal on the 16th June.
A further development authorised by an Act of Parliament
in 1830 provided a link from Fiddler’s Ferry to Wines Wharf on the west bank
of the Mersey and was completed by 1833.
The canal was designed for “Mersey Flats” a local sailing
boat, to accommodate the masts of which swing bridges were used rather than
the stone bridges of other routes, with the initial railways having to use a
similar type of bridge.
Pollution became a noted problem in 1877 when it was found
that mud deposits in places had an arsenic content of 2.26% due to the
outflow from the local Leblanc Alkali Works and the water was so acid that
iron and steel fittings could no longer be used. The problem of heavy metal
pollutants of local muds and soils persists until the present day.
While built initially to carry coal from the coalfields to
the Mersey, the reverse journey also became popular for the transport of raw
sugar to to Sankey Sugar Works at Earlestown providing a useful income after
the coalfield output had diminished
1845 saw the successful canal company merge with the St
Helens and Runcorn Gap Railway Company.
Sugar traffic on the canal ended in 1959 leading to the
end of commercial traffic on the canal and its closure in 1963, with some
swing bridges being replaced by fixed bridges.
Restoration began in 1980 leaving most of the canal now in
water, though some sections remain isolated where fixed bridges have
replaced the original swing bridges. The accessible sections have been
restored to navigable waterway.
