text: Just to provide some clarity to the comments here. 
  Currently (Sept 2018) the speed limit on the A52, from just east of its junction with the A520 at Cellarhead, is 50mph. This then reduces to 40mph at a point about 100yds just west of the junction with Bank Top Road. The 40mph limit remains until just before the point where the Waggon & Horses PH is currently marked on the map. Here it increases to 50mph. Continuing on the A522 towards Cheadle the 50mph limit remains until just before the JCB roundabout at which point the limit becomes 40mph. The limit reduces again to 30mph as you enter Cheadle just before the point where regular housing begins. Further on the A522 that limit remains right through the town until you leave main part of Cheadle town and move into Mobberley and becomes 40mph again towards Tean.
  
  All these speed limits were changed fairly recently (less than a year prior to Sept 2018) and all limits are sign posted.
