Does it have a harbour with sufficient cranes to offload it, and a good enough road to transport it out?

And if you're going to need 4 trucks to get it out of the port anyway, might as well just drive it there.

Sorry, no idea why I'm debating some random person on the internet about an issue which has absolutely no impact on me whatsoever. Sport, I guess.

There really isn’t a properly craned port per se. The transit time would be just as long, if not longer if it was crossed by barge.

It's a pretty big governance fail to have a single point of failure for access to an island.

There is redundancy in the form of a 90 minute Ro-Ro ferry route to the east, as well as mothballed docks near the bridge in case of an incident that closes the bridge completely. I’m not sure about the capacity for oversized loads on the ferry, but it’s often used by trucks to carry gravel and aggregate for construction.

more of a cost vs benefit tradeoff than a failure. It could also be just a SPOF for over-sized loads, whereas people have multiple routes on/off island.
