Norway has recently taken an interest in building a floating tunnel. Now they are in the race to build one. A floating tunnel is a submerged tube is a proposed idea for a tunnel that floats under the surface of the water. They plan for it to be deep enough to avoid boats other water traffic but not so deep they have to worry about water pressure. According to The Telegraph the tunnel that will be built in Norway will be “100 feet below the surface.” This will allow ships and boats to pass above easily but still room for submarines and water pressure safety. The tunnel will resemble two giant drinking straws.
Because of multiple breaks at seven fjords drivers have to put their car on a ferry to travel across water. The whole trip takes 21 hours, 21 hours is a long time. This is why they are now building a floating tunnel. The tunnel will allow the trip to be much faster and definitely more interesting. This construction takes a lot of work and a lot of time, this means that the tunnel won’t be ready anytime soon. Early February, 2019 it was reported at 10% done. It is said that by 2025 only about 33% of the tunnel will be done. It is expected to be completely finished around 2050.
Believe it or not but the idea of a floating tunnel has been around for a while. There have been more than 100 tunnels built immersed under water. That being said a floating tunnel is different, and this would be one of the firsts to be built. The idea has been available and out in the open for a while but nobody has actually built it before. The tunnel will be built well enough and strong enough to survive through natural disasters common in water. These disasters include wave currents, earthquakes, ice growth, and marine growth. The tunnel will also be held by bottom anchoring to make sure it can survive disasters.
