In Medieval times, Long Causeway was the middle of three routes which left Sheffield to the west. It started in the Portobello area of the town beginning a seven-mile journey with over 1100 feet of ascent to Stanedge Pole on the border between the manors of Sheffield and Hathersage. From Portobello the route continued by a series of rises and dips, climbing initially through Leavygreave and crossing the top of the Crookes valley and up Lydgate Lane (then called Hallam Gate) to reach which was then open moorland. The route then continued through present day Crosspool and followed the route along what is now Sandygate Road and Redmires Road, crossing the location of the present day Redmires Reservoirs before tackling the steepest ascent on the route up to Stanedge Pole.
