Just a thought I had recently whilst visiting Birkenhead. I understand that there are many factors that would influence such a project but I wouldn't rule it out completely. I believe it would greatly enhance the status of Wirral as a place to visit and would make getting there so much easier. I also believe it would make Wirral feel more like part of the Liverpool City Region.
Ofcourse it would have to be high so smaller ships could pass beneath and have some sort of draw bridge for larger vessels but I think this could be done. I would like your views
