Of course hikers and bikers could be accommodated too.
Also, having a barrage and using it for hydro generation does not require eliminating the tidal range upstream. Rather it gives an opportunity to control the tidal range so as to actively manage the salinity and hence the environmental health of the upper Mersey.
If the barrage were well South of the Seaforth docks but right at the Langton dock river entrance then the existing Langton cruise terminal could be rehabilitated to good effect as it would have direct access to the barrage and any ferries or etc. operating from it.
And finally, reclaimed land at the New Brighton end of the barrage could be used to build a new hotel - on the site of the old pier adjoining the prom. Join me in dreaming that we could call it "The Tower", put a ballroom in it and a smallish replica of the old steel Tower on top :-)
Has anyone got the talent, time and energy to sketch what it might look like?
Creating a barrage would mean the river would not need dredging and deep water ships could sail almost anywhere in time as channels would be dredged through - they would not fill up after being cleared as no tide to bring the sand in. Only the channels up to the barrage wold need dredging. The existing channels to the river have underwater training walls.
A barrage can have a road on it. Barriers stop traffic and/or trains when the locks are being used. An island in the middle could have a tower it, complete with restaurant, etc.

Well something like what Portsmouth did would be fine at New Brighton. This is a nice looking tower, called the Spinnaker as it is shaped like a spinnaker
