Still waiting on this one. You need to think outside the box and under the sea when you think tunnels.

Crossing the Bering Strait in between Russia and Alaska would require about 200km (125 miles) of undersea tunnel, the paper said, citing Wang Mengshu, a railway expert at the Chinese Academy of Engineering.
Hmm. A tunnel across a tectonic plate boundary (Eurasian to North American plates). Good luck!
