I can't see a suspended tunnel working out at all... it'd be expensive to implement, and we don't have the same amount of money that Norway has to fund all of its projects. Also, people have been proposing suspended tunnels for forever and yet no project of this nature has actually come to fruition yet...

A bridge at location #3, however? Totally doable. In fact I hope that they build it with a hollow under-truss deck, so that it can accommodate trains or extra lanes in the future... If we're actually going to be building this, we should do it right the first time.

As for a fixed link to Vancouver Island... the only approach I see working is building a long road and a series of bridges between Powell River and Campbell River. Such a detour would not be of convenience to people heading to/from Nanaimo or Victoria, but it could help economically diversify the northern part of the island via more reliable shipping connections. (And it should also accommodate single-track rail, imo)
