If you're coming up the M6, drop onto the M56 heading towards Chester & North Wales, come off at M56 J10 and follow A49 up into Warrington. You will go over a bridge and through various lights, until you will come to a mini roundabout with bus station on right, bear right following the main road over a large hump back like bridge, get in the left lane, you will hit some lights. You will see Mr Smiths night club on the left (the one the broadcast the Hitman and her from .. Micheala Strachen..hmmm... teenage memories), sorry, head past Mr Smiths, (you will also see signs saying Liverpool and Warrington Bank Quay Station). You will pass MFI, look for a turning on your left (about 100 yards before the train station on the bend, if you pass it, you've gone too far), you will essentially be turning back on yourself, follow road around you wil under a bridge, its on the other side :)
Make sense?
