(Grist) It seems like a fanciful idea — a bridge or a tunnel linking Russia and the United States. And people have been tossing the concept around, without actually doing anything about it, for a long long time. Czar Nicholas II, for instance, thought it was a good idea … in 1905.
But there’s a slim chance it could happen this time. Sure, it would cost a bundle ($100 billion-ish) and take at least a decade to build.
