FinEst Link Project



Are you interested in the Helsinki-Tallinn tunnel, twin-city development and new transport solutions?

Welcome to the FinEst Link project website!

Helsinki and Tallinn constitute an economic area of nearly 1.5 million people with busy traffic connections for people and freight. The twin cities Helsinki-Tallinn form an economic and logistic hotspot that is constantly growing. Last year the port of Tallinn welcomed its 10 millionth passenger. Both Helsinki and Tallinn handle growing volumes of freight, commuters and leisure travelers for the needs of the growing cross-border area between Finland and Estonia.

While the growing volumes of freight and passengers between the twin cities are a positive sign of interaction, they produce congestion and bottlenecks in traffic. The FinEst Link project explores the development needs in transport between Helsinki and Tallinn in a long-term perspective. On one hand the project analyses how the existing fast ferry services and connections could serve the increasing traffic volumes between the ports of Helsinki and Tallinn. The project also carries out a feasibility study that analyses from an economic and technical standpoint whether there are grounds for visioning a sub-sea railway tunnel between the two cities. The results of the project will be available in spring 2018.

The FinEst Link project (2016-2018) with a total budget of 1.3 million euros has received co-funding from the EU’s Interreg Central Baltic progamme. The project consists of six partner organizations in Finland and Estonia: Helsinki-Uusimaa Regional Council (lead partner), City of Helsinki, Finnish Transport Agency, Estonian Ministry of Economic Affairs and Communications, City of Tallinn and Union of Harju County Municipalities.

The FinEst Link project is built on openness and transparency. On this webpage you can find updates and results in the course of the project’s lifecycle related to, for instance, methodology, data, conclusions and recommendations.

Geological Survey of the Helsinki–Tallinn railway tunnel route

(20.2.2017) Geological Survey of Finland (GTK) conducted acoustic-seismic surveys of the possible linings for an undersea railway tunnel between Helsinki and Tallinn. The survey provides a detailed information of the geological structure of the sea floor between the two cities. To read more about the geological survey, click here.


The FinEst Link analysis is based on the following objectives

Improvement of the travel service to facilitate daily commuting between Helsinki and Tallinn
Including reduction of travel time between the cities to approximately 30 min, frequency of travel service, ticket price.

Smooth travel chains and integration with transport systems
Including integration of travel chains into the national rail networks, public transport systems in both cities, airports and Rail Baltic.

More effective freight transport chains
Including affordable travel service price, improvement of frequency, reliability and delivery time.

Improved environmental sustainability
Including improved energy efficiency, healthy urban environments and lower carbon dioxide emissions.

Improved safety and security
The transport solutions are safe and reliable.

Economic viability
The implementation model of the tunnel is based on minimal public support for the investment cost.
