This section of the Wyre Way runs North from the Wyre Estuary Country Park to Fleetwood via Burglars alley The discovery of vast deposits of rock salt below Preesall in the 19th Century led to the founding of a major salt industry on the banks of the Wyre estuary at Fleetwood, and the eventual development of I.C.I. Hillhouse International which can be seen today.
In 1890 natural brine was pumped across the river to the Fleetwood Salt Works, and by 1892 the first brine wells were drilled. Fresh water was pumped down the bore holes to dissolve the rock salt and the resulting brine was brought up to the surface. This was pumped across the river where it was used in the production of chlorine. A number of old brine wells are still visible around the Wyre. Mining of rock salt began in 1893 with skilled miners coming from Cheshire, and by 1906 production had reached 140,000 tonnes. The rock salt was transported by rail to a jetty by the river and loaded onto ships for export. The village of Preesall in Over Wyre made national headlines in 1923, when 5 acres of farmland vanished into a reservoir of brine almost overnight. Serious flooding of the brine wells became a problem and the mines were eventually abandoned in 1930. Further developments on site led to the founding of Imperial Chemical Industries, now commonly known as I.C.I. In 1941 I.C.I. became agents for the Ministry of Supply and started the manufacture of chemicals at the Hillhouse Works for materials required for the war effort. Since the war, many changes have taken place and the Hillhouse site now produces a range of materials and products used by millions of people throughout the world.
