A Memorandum of Understanding was signed on July 11, 2019 between FinEst Bay Area Development, TouchStone Capital Partners, China Railway International Group and GAMA for the construction of a 100 km submarine tunnel with an investment cost of 15 billion Euros to be built in the Baltic Sea.

GAMA, which brought the Marmaray Project connecting Asia and Europe to Istanbul, signed a Memorandum of Understanding to build the Tallinn-Helsinki Tunnel with the Chinese firm, which is intended to be the longest submarine tunnel in the world, within the scope of the “FinEst Bay Area Development ” project.

The 100 km Tallinn-Helinski submarine tunnel project, supported by the Finnish and Estonian Governments to ease heavy gulf ferry traffic, has a total investment of 15 billion Euros (US $ 16.5 billion) and is planned to be funded by Chinese financial company TouchStone Capital Partners and other international investors.

The tunnel project will be constructed by Gama together with China Railway International Group, which is in second place on the ENR listing, and TouchStone Capital. The project will bring together the cities of Tallinn and Helsinki underwater, which can be reached in 3 and a half hours by road and in 2 hours by ferry, under 20 minutes.
