Century project returns: tunnel between Eurasia and America

A statement about a possible tunnel between Chukotka and Alaska has once again brought back one of the most ambitious and widely debated infrastructure ideas of the past two centuries – a direct land connection between Eurasia and North America across the Bering Strait.

According to Russian presidential envoy Kirill Dmitriev, Russia and the United States are allegedly preparing to sign an agreement to continue the design of an 86-kilometer route that could pass under the Bering Strait. He said the document could be signed in the near future and would effectively launch a new stage of discussion of a project that has historically been referred to as a “bridge of peace”, a “tunnel of two continents”, and an “Eurasian-American corridor”.

Dmitriev’s direct quote reads: “As for the tunnel. We will have news tomorrow: we are signing an agreement that we are continuing the design of the tunnel. The tunnel will be built.”

The idea of connecting Chukotka and Alaska is not new. It first emerged in the late 19th century, when engineers and researchers discussed the possibility of building a transport corridor between Russia and the United States across the narrow section of the Bering Strait. At that time, the focus was mainly on a railway line that could link Asian and American infrastructure and create a new global trade route.

Throughout the 20th century, the project repeatedly returned to the expert agenda. Discussions were particularly active during periods of improved relations between the countries. Over the years, various options were considered, including a bridge, an underwater tunnel, and hybrid engineering solutions, but the project was consistently hindered by political disagreements, economic concerns, and extremely harsh climatic conditions.

The topic gained renewed attention in the 2000s and early 2010s, when international transport corridors and the integration of logistics chains between continents were being discussed. However, after 2014, negotiations were effectively frozen amid a sharp deterioration in political relations.

Now the issue is returning to the public sphere in the context of a potential resumption of engineering planning. According to Dmitriev, the current stage refers specifically to design work rather than actual construction.

Geographically, the Bering Strait is one of the most challenging regions for such a project. Its width in the narrowest part is about 80-90 kilometers, while environmental conditions include extremely low temperatures, strong winds, seasonal ice loads, and high seismic activity.

The economic aspect of the project also remains controversial. Supporters point to the potential creation of a new global transport corridor linking the rail networks of Eurasia and North America.

Opponents argue that the cost of construction and maintenance could be comparable to the largest infrastructure megaprojects in human history, while the economic return remains uncertain.

The political context is also significant. Any infrastructure project of this scale between Russia and the United States inevitably goes beyond engineering discussion and becomes part of international diplomacy.

Historically, the idea of connecting the two continents across the Bering Strait has been seen as a symbol of global integration. However, none of the previous attempts have reached the stage of actual construction.

Thus, the concept of a tunnel between Chukotka and Alaska is once again returning to the global agenda as one of the largest symbolic infrastructure projects in history, but between the announcement of a “design agreement” and real construction lies a vast distance.
