The transcontinental railway project, which will essentially connect Africa, Europe, Asia and both Americas, has been discussed for over 100 years. The first ideas to connect Russian Chukotka and American Alaska arose at the end of the 19th century. However, things did not go beyond words and newspaper articles.
Despite the rather strained relations between Moscow and Washington, the implementation of such an ambitious project will benefit most of the countries of the world. After all, this radically reduces the cost and simplifies the transportation of goods over vast distances. However, the construction of such a railway will certainly encounter quite objective difficulties.
The first of them is the construction of a bridge that will connect two shores - Chukotka and Alaska. And the point here is not at all the length of the bridge, but in very difficult climatic conditions. Ice movements, strong winds and low temperatures will require a completely different approach to the design of the structure.
The second problem is the practical lack of railways in both Alaska and Chukotka. However, both Russia and the United States are currently busy planning these. In any case, in the national strategy for the development of the railway network, the construction of tracks to the Bering Strait is already included.
