i drove over last year and found it relatively easy going.
come off the M62 at the widnes/st helens junction,follow the signs to st helens and stay on the dual carriageway until you see the stadium on your right hand side,further on up the dual carriageway at the first big roundabout ( after the stadium) turn right,go up this road under the bridge,turn left at next roundabout and entrance to car park is on left past the glass museum.
to get to the ground,come out of the car park,turn right back up the road you drove down,through the car park to glass museum,under a bridge,onto the bridge over the road,and past tesco and the ground is there.basically follow the crowds!
be warned though,the bridge gets pretty busy after the game as 10,000+ people are trying to get onto it!
see you all there and bring your voices!!
