Ship tunnel: Norway is set to build what's billed as the world's first ship tunnel, to help vessels cross the notoriously rough Stadhavet Sea.

Ongoing project: The project has been in the works for a while, but now has the go-ahead and construction is set to begin in 2022.

Interior rendering: Inside, the Norwegian Coastal Administration says the tunnel will resemble "a large and long mountain hall."

Stadhavet peninsula: The tunnel will be burrowed into the Stadhavet peninsula. "The coastline outside that peninsula is the most stormy area in Norway, with the hurricanes," temporary project manager Terje Andreassen tells CNN Travel. "You get a lot of strange currents here."

Safer crossing: The idea is vessels will be able to more safely cross the Stadhavet Sea within the tunnel, as tide changes won't impact water here.

Coming soon: The construction process is expected to take between three to four years.
