AN UNDERGROUND TUNNEL BETWEEN RUSSIA AND ALASKA? Now there’s an engineering project for you. Hard to believe there’d be sufficient traffic to justify it, but . . . .

UPDATE: Stephen Gordon at The Speculist thinks that there would be enough traffic. Problem is, it’s a long way from anywhere. It’s nice to connect Siberia and Alaska — making it, as Phil Bowermaster notes, possible to drive from Paris, Texas to Paris, France. But Alaska itself is a long way from anywhere, and there aren’t even rail and road connections to the Bering Strait areas where the tunnel would go.
