Norway is building the world’s first ‘floating’ underwater tunnels

Norway has an ambitious plan to ease the congestion of local ferries by building a series of underwater tunnels that allow travelers to cross the nations bodies of water.

The “submerged floating bridges” would consist of large tubes suspended by pontoon-like support structures 100 feet below water. Each will be wide enough for two lanes of traffic, and the floating structures should ease the congestion on numerous ferries currently required to get commuters from Point A to Point B. Each support pontoon would then be secured to a truss or bolted to the bedrock below to keep things stable.
