The platform, made from modular 40ft shipping containers, gives visitors a view of the job site near Puttgarden from a height of 6m.

The structure is part of Sund & Bælt’s aim to inform people about the construction of the world’s longest immersed tunnel.

On clear days, the view extends to the tunnel element factory at Rødbyhavn on the Danish side. Two pairs of binoculars provide a better view, while information boards and films explain the construction of the tunnel. The platform is powered by a photovoltaic system.

“With the new viewing platform, we are creating a great opportunity to experience the construction work on the Fehmarnbelt Tunnel up close without entering the construction site,” said Lars Friis Cornett, director of Femern A/S in Germany. “It complements our existing Infocentre in Burg on Fehmarn, which will continue to be the primary hub for comprehensive information about the project. We are delighted to be able to offer people even more insight into the construction of the Fehmarnbelt Tunnel with this new attraction.”

The platform at the German construction site follows the opening of a 217m-long structure in Demark in March. Known as Pilen, or the Arrow, it gives visitors a 24m-high vantage point over the site at Rødbyhavn.
