FinEst link investigated whether it’s realistic to build a fixed link (tunnel) over the Gulf of Finland between Helsinki and Tallin. Upon project completion, the following results were produced:

1. Technical concept of a railway tunnel (1435 mm gauge railway tunnel with two rail tunnels and service tunnel)
2. Cost estimation for building the tunnel (13-20 billion euros)
3. Estimates for demand volumes of passengers and freight (passangers in 2050. Without tunnel, 14 million, with tunnel 23 million)
4. Cost-benefit analysis (B/C ratio is 0,45)
5. Economic impact analysis (impact on GDB between +4000 – +6900)
6. Planning objectives (daily commuting, travel chains, freight, environmental, safety and security, economic viability)
7. Strategic positioning of the railway tunnel in the TEN-T policy framework (direct continuation of Rail Baltica)

As an additional result of cooperation between Finnish and Estonian experts and officials, high level political cooperation was initiated as well. This is an important step for developing the idea further.
