The Russian Government has given the go-ahead to build a $65 billion transcontinental railway linking Siberia with North America. The project aims to feed North America with raw goods from the Siberian interior and beyond. A renewable energy transmission corridor will also be put in that feeds wind and tidal power across vast distances. The tunnel through the Bering Strait will be the longest tunnel in the world and would cross the International Date Line.
