In reply to Jon Stewart: Jon, checkout the route which goes out over Winnats Pass, Chapel, near to Windgather, then Pott Shrigley and Wilmslow, joining the M56 near Manchester Airport. It's the one the drivers seem to take to do airport drops from Sheffield.
There is also a little rat run which goes from the far end of Gloss*p and comes out at the roundabout at the beginning of the M67 which is handy on the normal route.
If however you drive an Audi or a Beemer, you can plough up the outside lane towards Mottram, then barge your way into the left lane at the lights because it's your right. Apparently.
