While there is still a lot of work to be done in terms of exploring the geology of the area, doing risk analysis of possible ship collisions and figuring out how the natural environment (winds, waves and water currents that can cause driving discomfort or traffic disruption) could affect the floating tunnels, chances are that a permanent crossings across the fjords would come to life by 2035: Norway is seriously considering building ambitious submerged floating tunnels that actually act as underwater bridges.

The system, each consisting of two tubes to allow traffic in both directions, would be located approxiamtely 100 feet below the surface, suspended by floating pontoons. 

According to researchers, driving through a submerged floating tunnel wouldn't feel any different from traveling through an ordinary tunnel, but just knowing you're surrounded by water above and beneath you could make some passengers feel a bit uneasy. Still, the new bridge system would save a lot of time and make travel across (instead of around) many fjords far less complicated.
