  1. They are doing that already...

  2. It would have been faster to not built it under the sea floor (lot of digging) but in the water 50m below sea level. Norway is planning to construct a floating tunnel this way through fjords.

  3. It connects noone to nowwhere, and you need first lay 3000 km of rail through the coldest and harshest environment on earth. If it gets built it is not before 2040 or later. First they should do Sakhalin to mainland russia bridge or tunnel and then connect Sakhalin to Japan (not planned yet, political not viable at the moment).
