discussed the nuances of a 'new' supermarket in Marple with counterparts/ friends/ colleagues who live in Glossop or Poynton, both of which remain vibrantI haven't heard anyone from Glossop or Ponton who think that the new supermarket developments in these towns have beneficial. In fact I've spoken to a number of people who use to shop there who now travel to Marple instead.
Also both Glossop and Poynton from a traffic point of view have become NO GO areas.
The Glossop traffic NO GO issue is nothing to do with the Tesco, or any of the other shops, it's simply because the main road through the centre of Glossop is the A57, AKA the Snake Pass, one of the two main routes from Greater Manchester over to Sheffield. The traffic in the centre of Glossop was noticeably absent during the recent cold snaps, when the Pass was closed.
And as for Poynton, isn't the main route through there the main artery linking Macclesfield to Stockport/Manchester?
Both towns had major traffic problems prior to the supermarkets, and would continue to have them long after were they ever to shut.
