Like so much of the stuff surrounding the college/supermarket issue, this is pure speculation. It's based on the possibility that if a planning application is submitted for the construction of a supermarket in Hibbert Lane, and in the (fairly unlikely) event that it is approved, the Council might
impose a condition on it that the Hibbert Lane/Stockport Road junction must be rebuilt to cope with an increase in traffic, and that this rebuilding might
entail a roundabout, which might
just be so big that the baths would have to be demolished. On the other hand, the council might do nothing of the sort..........
If this improbable scenario were to happen, however, it would probably be good news, because the council would almost certainly require the developers to fund the construction of new swimming baths on another site. Like, er, Hibbert Lane?
