Think of a drinking straw, anchored in the bedrock on either side of the fjord, submerged about 98 feet below the surface of the water, low enough for the biggest ships to pass safely over, and with plenty of space underneath for submarines to come and go.
In addition to staying clear of water traffic, the depth of the tunnel assures smooth driving. "Wind, waves and currents have hardly any influence there," Arianna Minoretti, a chief engineer at Norway's Public Roads Administration, told ABC News.
She said 50 international experts "are doing detailed simulations and detailed measurements of wind speed, current, undersea landslides, bedrock geology, etc." to make sure the plans, as well as the tunnel, is rooted in "the real-world environment."
The two concrete tubes of the tunnel -- one for traffic headed in each direction -- will be firmly fixed in position and attached to floating pontoons, spaced 820 feet apart to allow sea vessels to pass through.
