Floating Tunnel In Norway?

Looks like an interesting concept here, excerpt from the article:

The Norwegian coast may be beautiful but with more than a thousand fjords cutting into it, getting from one place to another often requires lengthy journeys.

Norway’s Public Roads Administration (NPRA) has an ambitious plan to solve the problem by building the world’s first floating submerged tunnel system about 30 meters (100ft) underwater.

It's certainly a clever idea, not too sure how they plan to account for potential large amounts of traffic, but provided it's buoyant enough it certainly sounds like it could work, and we could potentially see a few more of these in future!
