I really think these islands DO NOT need mainland bridge connections....

Marthas Vineyard
Nantucket
Block Island
Newfoundland
Mackinac
San Juan Islands
Catalina
Vancouver Island

and I also don't think the Hawaiian islands need inter-island bridges either. Somebody suggested a bridge from Maui to Molokai. Uh yeah......that would fly well with all the natives on Molokai, the locals would love that!

In most of these cases the distance is so wide and the ocean so deep that such a bridge would be an engineering impossibility.

Well yes, and I knew that as I was typing, but nonetheless I appreciate their true island character and hope they remain that way, so... there's that.

Also, it wouldn't be a monumental task to build a bridge to Marthas Vineyard. And there are enough resources that could be extracted from Vancouver Island along with desirable land to warrant a bridge crossing. I hope it never happens though. It's also plausible to build a bridge from Blanc Sablon, Quebec to the northern tip of Newfoundland.

Vancouver Island for sure. In this pic from Street View you can easily see mainland BC on the other side of the water (https://goo.gl/maps/XfV8T).

Though I doubt there will ever be a bridge between Quebec and Newfoundland. It's just too isolated and the distance between the two (I'm guessing about seven miles) is pretty substantial.

That bridge is almost entirely a viaduct. It's a whole different animal building a bridge over water than over land. The longest bridge over water is the Lake Pontchartrain Causeway, which is about 25 miles.

Exactly.

And, Lake Pontchartrain is only 12 feet deep on average, which is completely different then building bridge that has to reach down hundreds of feet to the bottom of the ocean or a great lake.

Also, even on Lake Pontchartrain there are problems with people running out of gas on the middle of the bridge, people getting caught on the bridge in the middle of a summer thunderstorm, and car accidents caused by sudden fog. Again, this would all be exacerbated on a longer bridge over a more unpredictable body of water.

There was a study done fairly recently (within the last 10 years) for a proposed bridge from Northern Newfoundland to mainland Labrador (within the vicinity you're referring to..near the Quebec border) and the only way it would be feasible was to construct a tunnel for a single rail line..

Too much money, too deep of a channel and not enough population to justify even that.

Not surprising, though I didn't think the interest in building the tunnel's primary purpose would be based on connecting sparsely populated areas. There has been an uptick in offshore oil production off Newfoundland along with exploration of shale natural gas extraction on the island.

Consider all the roads and infrastructure built in some of the remotest parts of Alaska to accommodate the needs of energy production and transport. Just saying, depending on how much oil and gas they can get from Newfoundland, building mainland bridge or tunnel connections to the island could be plausible in the future.

you could build the bridge across the backs of the whales in the channel

From November to April, that's true.
