It appears that there is no land route to the entire peninsula, the only way to get there is by ferry.

Where I come from, we call those islands...

Seriously, though, I can see no justification for this extraordinary expense. A new road off the PENINSULA to a new airport could probably be built cheaper. It is just another transfer of wealth...

What I meant when I wrote that was that there are no roads through the mountains in the upper portion of the peninsula. On closer inspection, what I thought was a peninsula actually is another island.

Agreed. If it's important, let the State and local governments build it and pay for it.
