A blue sign with a diagram showing a branch off the road ahead and the following text.
Forward destinations: Birmingham; Liverpool (M58).
Exit destinations: Wigan; Parbold; A5209.
Junction number: 27.
Wigan's quite a big place now, and getting there from here involves a trip through Standish, so if you're exiting the M6 in search of pies you might like to use junction 26.
