Friday, the Strava route it suggest to me uses this bridge, I didn't realise it was limited to weekends? I can't load the route from your link for some reason....What day of the week are you planning on going? If at the weekend then you can ride over the Silver Jubilee bridge in Runcorn, which makes the run much easier to plan - I'd use something like this as it avoids the worst of the hills and through Warrington, Runcorn and Chester through to Deeside keeps you on off road routes where it makes the most sense - and avoiding an awkward cycle route through Frodsham.
