Best Route to Bromborough, The Wirral from the North East

[Paul S4]

Not sure if this is the place to ask....!

I have to travel to Bromborough in the Wirral for 9am and will be driving down from Co Durham.

Apparently it is quite near the south end of the Mersey Tunnel.

I have never been to Liverpool before, so wondering which is the best way to go bearing in mind I have to get there for 9am.... rush hour traffic etc(!)
