|The FinEst underwater tunnel running between Tallinn and Helsinki will be a record 100 kilometres (62 miles) long. Two tunnels, with a diametre of 17 metres (55 feet) each, will be crossed by high-speed trains cutting travel times between the Estonian and Finnish capitals from two hours to just 20 minutes. The project’s estimated cost is between €13 billion and €20 billion, most of which will be covered by an investment by the Chinese government fund Touchstone.
The project was born back in the 1990s, and received European Union funding for a feasibility study. In February 2019 the Finnish Transport Minister Anne Berner said the country would join plans for a Baltic railway connecting Estonia with Poland. This was seen as a step forward towards building the tunnel. Construction times are unclear, although the developer FinEst Bay Area Development’s official website indicates that the works could be completed as early as 2024.|
