The Trans-Eurasian Belt Development was presented by the head of Russian Railways, Vladimir Yakunin at a meeting of the Russian Academy of Science, according to The Siberian Times.
If built, the highway would be the longest road in the world. A road trip from one end to the other would be more than 20,000 kilometers long. Building costs for the superhighway and accompanying high-speed rail is estimated to be in the trillions, but Yakunin insisted at the meeting that the project would pay for itself in rapid economic growth for Russia's remote interior.
The project faces many challenges, including connecting the farthest reaches of Russia to the vast empty countryside of Alaska, where there are few roads, let alone massive engineering projects. Russia has tried several times to bridge the turbulent Bering Sea, but various projects have failed to get off the ground, according to The Washington Post.
