Crossing Norway's fjords is going to get easier with world's first submerged floating tunnel. The tunnel would sit about 100 feet below the surface of a fjord. By Dragana Jovanovic.

The tunnel highways would be submerged about 20m below the surface. The structure is officially called a submerged floating tube-bridge but is also known as a Archimedes Bridge.

These structures rely on a delicate balance between hydrostatic buoyancy and gravitational ... The graph below shows the total number of publications each year in Submerged Floating Tunnel Dynamics.

This description might go some way to explaining the dizzying array of names given to this structure – officially called a submerged floating tube-bridge (SFTB), it’s also known suspended ...

A huge infrastructure project in Norway to overhaul the country's Highway E39 includes a proposal to build the world's first submerged floating tunnel.

All that may change if an ambitious engineering project comes to fruition. The small Nordic country has announced plans to spend a reported $25 billion on a fully submerged, floating tunnel ...

The submerged floating tube bridge is one of the possible structures that we are evaluating for several of these fjords. AS IT HAPPENS: Oddly placed Holland Tunnel decorations spark anxiety, road rage ...

A submerged floating tunnel would sit around 40 meters ... Floating bridges – structures that are supported by pontoons – have been built in Norway and the US, among other countries.

Submerged floating tunnels (SFTs) represent an innovative approach to overcoming deep-water crossing challenges by combining buoyant and mooring systems with advanced design and construction ...
