Immersed tunnels

The immersed tunnel (or immersed tube) is a tunnel construction method commonly used for crossing a body of shallow water. The method has been widely used for about 100 years, and more than 150 immersed tunnels have been constructed worldwide. They mainly serve as road or rail tunnels, but immersed tunnels are also used for water supply and electric cables. Ramboll provided professional services to a wide range of immersed tunnels worldwide.
