Greetings fellow AHistorians!
You may have seen my earlier thread regarding a
Trans Atlantic Tunnel which pretty much devolved into bickering and arguments (much to my amusement

). I did learn a large amount from it and it led me to thinking. What if this was attempted on a much smaller scale?
Namely, an Anglo-Irish bridge or tunnel.
It has been proposed before and apparently £15,000 was contributed to the project in 1897 to see if it was viable. I dont know what the results were.
Here is a link to the
wiki article.
But yes! Here is my question.
With a pod of 1890 (when it was first proposed), can we see the creation of a bridge or tunnel that connects the British Isles?
How could it be done? What route would be chosen?
Whats the earliest it could be realistically completed?
How would it affect history? Maybe something as significant as keeping Ireland as part of Great Britiain?
