After more than a decade of planning, construction of the Fehmarnbelt tunnel began in 2020, following the completion of a temporary port on the Danish side. It will house the factory that will soon build the 89 massive concrete sections that will make up the tunnel.

"By the beginning of 2024 we should be ready to sink the first part of the tunnel."

It will be built along the Fehmarn Belt, a strait between the German island of Fehmarn and the Danish island of Lolland. It is designed as an alternative to the current ferry service from Rodby and Puttgarden, which they carry passengers every year.

The tunnel, whose official name is the Fehmarnbelt Fixed Link, will also be the world's longest combined road and rail tunnel. It will include two dual-lane highways and two electrified rail lines.

"Today, if you took a train trip from Copenhagen to Hamburg, it would take you about four and a half hours," says Jens Ole Kaslund, technical director of Femern A/S, the Danish state-owned company responsible for the project. "When the tunnel is completed, the same journey will take two and a half hours." The Best Technology Site in Greecefgns
