The roads in Marple centre cannot take any more heavy traffic, such as HGVs delivering to new supermarkets.
If a new, and large, supermarket is built on Hibbert Lane the only way out for ALL traffic is back to Stockport Road, adding to congestion already present at the traffic lights.
When Samuel Oldknow built his 'New Road' in the 1790's he had horse and carts in mind. It has done very well so far, but enough is enough. And it is time the planners realised this.
