Have you used the Mersey gateway bridge yet?
I have and found it to be a very convenient way of getting to the M6. Of course you have to pay the toll fee but I found that's very easy. On balance I prefer to pay the fee in advance otherwise I'm always concerned when I've arrive at my destination I forget to retrospectively pay the fee.
When I've used it, it’s never occurred to me to think about the banks on either side of the Mersey, after all. driving is demanding enough to spend any time reflecting about it. However, recently I came across this video and loved it. It's made by Alison Hitchens and tells a story of the ecology of the River Mersey banksides.
Incidentally. as I watched the video I recalled my own very small adventure in the early '60s. As a student civil engineer, working for British Railways, LMS Region, I nearly fell off the bridge as I dived into the lattice girder work to avoid a speeding, steam driven express, hurtling out of Runcorn Station on it's way to Lime Street.
I hope you enjoy it as much as I did.
With the completion of the Mersey Gateway, this short documentary takes a closer look at how wildlife on the surrounding estuary has been affected by the construction of this colossal bridge, and reflects upon our choice to live alongside nature.
