FIRST SUSPENDED IMMERSED TUBE TUNNEL MAY BE BUILT IN NORWAY

The possibility of constructing the world's first suspended immersed tube, or submerged floating concrete tunnel in Norway is examined. Although similar to a conventional immersed tube tunnel, occupying a dredged trench on a river bottom, the suspended immersed tube tunnel has to be suspended below the surface at a sufficient depth not to endanger navigation. Such a tunnel is securely located at both ends and anchored from two control points to the river bed. At sites in Norway where a conventional road tunnel through bedrock would be too expensive, a suspended, immersed tube tunnel floating below the surface would satisfy a demand for a permanent road connection.
