Construction
The largest tunnel module factory in the world was built from scratch on a beach in Denmark to produce 89 concrete blocks and will be demolished after the project: each structure weighs up to 10 times the Eiffel Tower and will be installed on the bottom of the Baltic Sea with an accuracy of 12 millimeters in a tunnel that will halve the travel time between Hamburg and Copenhagen.
