Messina, Brad! Messina! Oh, sorry.
There's been talk for a really long time about such a bridge. The parliamentary gubmint of Italy tends to fall a lot, and there's a big divide, believe it or not, on whether such a project should be undertaken.
If memory serves, Italy has actually tried to sell bonds to finance the project several times, and each time the gov't fell before very many were sold, so the money raised just went into general funds.
The current plan is for a huge-ass suspension bridge.
IMHO some Korean or Japanese (or whomever Norway uses) company that prefabs tunnel sections, sinks them, links them all together, then pumps out the water should be availed of. While the discussion about the bridge goes on, the link could have been completed years ago.
The maximum depth reaches over 800ft. That’s a lot of pressure for a drop-in tunnel.
