Spain says a feasibility study for an undersea tunnel to connect Spain and Morocco is in the final stages.

Swiss engineers are finalising a feasibility study that will determine whether this underwater connection is technically possible.

If the project goes ahead and construction begins, trains carrying both passengers and goods are expected to start using the tunnel in 2025. The tunnel would be 40km long and pass 300m under the Mediterranean Sea.

If the feasibility study is positive, work on the tunnel could start in 2009.

A little like the Tunnel between France and England discussions have been ongoing for more than 20 years.
