Helsinki Tallinn FinEst Tunnel #RayHaber

The 100-kilometre tunnel would cost between €13 billion and €20 billion, practically a little less than Estonia’s annual gross domestic product of $26 billion. The tunnel would be longer than the Channel Tunnel (54 kilometres, or 31 miles) which links London with Calais. The work is being developed with China’s promised backing by a private group called FinEst Bay Area Development, founded by Finnish gaming entrepreneur Peter Vesterbacaka, which has signed a memorandum of understanding with Touchstone Capital Partners owned by the Chinese government. The underwater tunnel will have an intermediate stop on an artificial island where a real estate development will house skyscrapers, buildings and green spaces.
According to FinEst Bay Area Development’s website, the two tunnels will have a diameter of 17 metres (55 feet) and will be completed in a record time of under 24 months, while a delivery date has not been set. The Helsinki-Tallinn task force carried out a feasibility study in 2014 that estimated a 15-year completion time – quite a sizeable difference. The company that carried out the study pointed out that times could be greatly reduced given large investment levels, arriving at a possible conclusion of the work as early as 2024. Even this would be a truly difficult goal to achieve for a massive work that has been in the planning stages since the 1990s.
