Plans for a tunnel linking Bolivia to the Pacific Ocean have been unveiled by three architects who say it could put an end to a 130 year-old dispute between the landlocked country and its neighbour, Chile.The tunnel would be 93 miles long and run from the Bolivian border to an artificial island created in the Pacific Ocean from earth dug to build the tunnel.
It would be good news for the Bolivian navy, if no one else.
But that is nothing when you read about what might have happened in communist Czechoslovakia.
Again according to the BBC, there were plans to build an underground rail link under Austria to the Adriatic. This one would have been 255 miles long and, again, the spoil would have been used to build an artificial island - this one with an airport on it.
