Lidls plan offer 2 entrances but no improvement alteration to the present traffic lights nor the width of the road for HGVS to turn left around on the corner.
Nettos plan has 1 entrance by a new slow curved wide slip road and replaces the lights to what so many people have complained they should be, a full 4 way system that can only ever be built by obtaining some land.
Hope that makes things a little clearer.
