The World's Longest Tunnel

fusconed writes "Bloomberg reports that the Russian government is proposing to build an underground tunnel between Russia and Alaska for transporting goods, electricity and natural resources. The tunnel would be twice as long as that between the UK and France. The $10 — $12b cost is not something to be overlooked, but Russia claims the benefits would pay it off in 20 years. It would take 10 to 15 years to build, but being an Alaskan, it sounds good to me!"
