Brindley's Harecastle
Tunnel took from 1766 to 1777 to complete - eleven years in all - it
took 600 miners and masons and was built using a line of shafts that
were dug across the length of the tunnel, then these were joined
together to form the tunnel. The shafts dug ranged from 210 to 240 feet
deep. Miners were lowered down on ropes to dig, and the builders were
fraught with many a hazard, from bad air in the shafts, water ingress
into the tunnel, to quicksands, the build up of gasses from coal seams,
to the encounter of rock harder than anything that he had ever come
across before, such as granite and millstone grit. Many of the miners
lost their lives in the building process. This second tunnel had a towpath so that horses could pull the boats through the tunnel. After its construction it was used in conjunction with the Brindley tunnel with each tunnel taking traffic in opposite directions.
