205,000,000,000 dollars - how much will it cost to build a tunnel between Russia and the USA? Conservative analysts have estimated the cost of building a tunnel under the Bering Strait between Russia and the USA at 205 billion dollars. The project includes the creation of a transport crossing of record length, which should connect the Russian territories with the USA. Experts also analyzed possible timetables for implementation and options for tunnel construction. They point to the Diomede Islands in the Bering Strait as one of the advantages of the track, which could play an important role in laying the track.
