The tunnel between Russia and the USA through the Bering Strait was estimated at 16.7 trillion rubles. The construction of a railway tunnel between Russia and the United States may cost about 205 billion dollars (about 16.7 trillion rubles). Analysts give such estimates. One of the main problems of the project will be the lack of railway infrastructure in Chukotka and the lack of necessary tracks in Alaska. In fact, a significant part of the railways will have to be built from scratch. According to realistic estimates, construction will not end before 2041.
