Plans for an Undersea Tunnel Between Morocco and Portugal
The Strait of Gibraltar serves as a narrow divide between Europe and Africa, measuring just over 14 kilometers at its shortest point between Spain and Morocco. While the idea of constructing a bridge across this slim stretch of water may seem like a dream, plans are underway for an undersea tunnel that would facilitate passage beyond mere ferry services. This ambitious project is not the only initiative being considered by the Moroccan government, as discussions are also in progress to create a megastructure that would link the Iberian Peninsula directly with Portugal.
Currently in the preliminary stages, this project aims to connect Morocco and Portugal through an undersea tunnel expected to be operational by 2030, as detailed by Fakta 24. The proposed infrastructure would link northern Tangier with Portugal’s Algarve region, featuring a dual-tube design that includes separate lanes for each direction and an emergency technical corridor. This underground highway would integrate with Portugal's A22 highway, thereby enhancing accessibility.
A Transformative Construction with Global Implications
The scale of this proposed construction would significantly alter the Atlantic landscape and create an unprecedented link in the world. Despite the lack of official confirmation regarding the feasibility of this project from both countries, negotiations between Portugal and Morocco have been ongoing since 2021. Discussions centered on establishing a maritime route between the Port of Portimão in the Algarve and Tangier were highlighted by Portuguese Minister of Economy, Pedro Siza Vieira, who expressed interest from both governments in advancing this collaboration.
The Portimão route, a key destination in the Algarve with facilities capable of accommodating large vessels, could not only bolster tourism in both nations but also revive a long-considered trade route. However, logistical challenges, such as the more than seven hours required for the crossing and the associated costs of managing arrivals and departures at the Algarve port, have led to multiple suspensions of the project. Nevertheless, there is renewed optimism, as reports suggest that efforts may recommence to realize this ambitious dream.
Beyond enhancing direct connectivity between Europe and Africa, this initiative would substantially boost trade and logistics, strengthen bilateral cooperation, and elevate the international profile of both countries. Furthermore, establishing a connection between Portugal and Morocco could set a precedent for a future tunnel linking Morocco with Spain, facilitating seamless communication between Moroccan and Spanish territories via Portugal.
However, significant challenges remain, particularly concerning the Camarinal Sill, a critical point that complicates the construction of a megatunnel between Spain and Morocco. Experts have concluded that such monumental projects are fraught with difficulties, notably due to strong Atlantic currents, which, according to a study by the Geological Society of Spain, create a cyclonic whirlpool over the continental margin near Spain and present an irregular and deformed terrain.
This technical complexity explains the absence of existing infrastructure, such as a bridge, between Spain and Morocco, despite their proximity. The Institute of Engineering in Spain has noted that beyond economic and geopolitical considerations, technical challenges persist, including depths of up to 900 meters and powerful marine currents. Additionally, the Strait of Gibraltar is a seismically active region due to the convergence of the African and Eurasian tectonic plates, compounded by adverse weather conditions like strong winds, which could further complicate the construction and maintenance of a potential bridge.
