Engineers plan Europe-Africa tunnel across Strait of Gibraltar

A major new proposal aims to build a tunnel connecting Europe and Africa. This ambitious project could allow travelers to take a train from Spain to Morocco without using a boat or plane. Experts believe this tunnel could be the most significant infrastructure project yet. Construction expert Bill Bencker discussed the challenges of creating such a tunnel. He highlighted that the best route would likely be across the Strait of Gibraltar, which is about 8.7 miles wide. However, the depth of the water in this area reaches over 3,000 feet, making it more complex than other tunnels like the Channel Tunnel. Bencker explained that constructing the tunnel could take 15 to 25 years. This timeframe includes planning, environmental studies, and securing funding. For context, the Channel Tunnel underwent four years of discussions before construction began. The estimated cost of the tunnel ranges from £42 billion to £84 billion. This is significantly higher than the Channel Tunnel, which cost about £11.7 billion in today's money. Bencker also warned that costs could rise due to unexpected challenges during construction. While technology exists to build such a tunnel, there are broader issues to consider. Trade and tourism between Europe and Africa show potential demand. However, political factors, security, and migration policies could complicate or hinder the project. Overall, the tunnel is feasible, but realizing it will take time, cooperation, and substantial financial investment from both Spain and Morocco.
