A 60-kilometer rail tunnel could connect Morocco to Spain by 2040. Led by Rabat and Madrid, this project aims to strengthen trade between Europe and Africa, with technical studies currently underway to validate its feasibility.

The rail tunnel project under the Strait of Gibraltar, linking Morocco to Spain, has reached a new milestone with the launch of essential technical studies. Estimated at €15 billion, this 60-kilometer-long infrastructure—28 kilometers of which will be underwater—could become one of the most ambitious tunnels in the world. It would connect Tangier to Algeciras and sustainably strengthen connectivity between Europe and Africa.

Led by the Spanish company SECEGSA, the project is currently based on two feasibility studies. One, entrusted to Herrenknecht Ibérica, focuses on the geotechnical conditions of the Camarinal weir.

The other, led by Tekpam Ingeniería, focuses on seismic monitoring. Results are expected by September 2025. To date, nearly €4 million has been allocated for this initial phase.

The tunnel would be built in two stages: an initial single-track tunnel for trains, followed by a second tube to separate the flows. If completed, this strategic link could boost trade, tourism, and investment between the two shores of the Mediterranean. It is expected to be operational by 2040. The project relies on close cooperation between Morocco, Spain, and the European Union.
