According to the report, which cites a single expert at the Chinese Academy of Engineering, Chinese officials “are considering a route that would start in the country's northeast, thread through eastern Siberia and cross the Bering Strait via a 125-mile long underwater tunnel into Alaska.” This sounds fine, until you realize the proposed undersea route is longer than the Chunnel and the Seikan Tunnel in Japan (currently the world's longest and deepest) combined.
Both were amazing feats of engineering in their own right, and that was without four major world governments (two of which don't play very nicely together) in the mix. Unsurprisingly, “[n]o other Chinese railway experts have come out in support of the proposed project. Whether the government has consulted Russia, the US or Canada is also unclear,” reports the Guardian. It's worth pointing out that Russia did green light a similar project in 2011.
While we're inclined to file this one under ‘strange and unusual news' for the time being, it's interesting to note that if anyone could create something as preposterous as an undersea railway around the world, it's China. “In the last half decade or so, China has embarked on an astonishing rail construction spree, laying down tens of thousands of miles tracks and launching myriad high-speed lines,” explains the Washington Post.
