Finland and Estonia are planning to create a rail freight bridge between the country and Estonia. The three options being considered include the construction of an under sea rail freight tunnel under the Gulf of Finland to Estonia at an estimated cost of €1.5 billion.
A rail freight and passenger tunnel is also being examined which would cost an estimated €42.5 billion. A third option under review is to create a freight bridge between Finland and Estonia supported by cargo-based commercial train-ferry services.
