Have been on it twice now. Incredible road. 2am and a Monday at about 2-3pm and both were running free and empty. Main route from Ferry to anywhere south.
Been on it three times and it was a joy each time. No worries paying the £3.50 for the pleasure of driving, rather than 'free' queuing. Same way as I dont resent paying £1.20 each way in the Mersey tunnel.... albeit the latter has a SUPER aural freebie
