A Spanish government committee has confirmed that a proposed project to build an underwater tunnel connecting Spain and Morocco is a viable project.
The largest tunnel-construction company in the world, Herrenknecht, teamed up with the University of Zurich to conduct a feasibility analysis, The Local reports. Despite worries over construction challenges, they concluded that the 18.6-mile-long tunnel between Europe and Africa can reasonably be constructed.
The total price tag is estimated at €8 billion. The first step would be to construct a custom-made boring machine at a cost of €32 million.
The tunnel would be used to transport high-speed trains, and also to transmit solar energy generated in the Sahara desert to Europe. Nearly 17 miles of the tunnel would be submerged below water, reaching depths of 1,558 feet below sea level.
Those wishing to travel between Spain and Morocco generally travel either by plane or by ferry. Ferries launch from Gibraltar and Tarifa in Spain and land in Tangier or Ceuta, an autonomous Spanish city on the northern coast of Africa that is just 7.1 square miles.
