Siberian–Alaskan Railroad – a project of transport channel across the Bering Strait, presuming costruction of 4,000-km railroad, that would connect Trans-Siberian Railway, Baikal-Amur Mainline and Yakutsk, and a railroad bridge across the Bering Strait to Alaska, United States. Construction of the railroad bridge would connect transport systems of Europe, Asia, and North America. Estimated construction cost is 50–60 billion dollars. After S. A. R. construction, Trans-Siberian Railway will partly take cargo turnover between North America, Europe, and Asia. The implementation of this intercontinental channel lies far in the future.
