Engineering firm Arup has designed a demountable, arrow-shaped viewpoint named Pilen in Denmark to offer the public a view of the massive Fehmarnbelt Tunnel construction site. The 18-kilometre-long road-and-rail tunnel is currently being built underwater to connect Rødbyhavn in Denmark with Puttgarden in Germany.
Commissioned by contractors Femern, this striking structure helps the community understand the immense scale of the project. For professionals interested in how temporary structures influence public perception, exploring broader architecture articles can offer wonderful comparative insights.
Engineering the Arrow
Meaning “the arrow” in Danish, the Pilen viewpoint evokes a compass needle pointing directly toward the German side where the tunnel emerges. Measuring precisely 217 metres long, the ramped structure mirrors the exact length of each of the 89 individual concrete elements making up the world’s longest tunnel of its kind.

Design and Sustainability
A fully accessible, landscaped walkway zigzags through greenery on the timber-and-steel deck, rising 24 metres above sea level. The site was strategically chosen to maximize visibility of both the construction work and the surrounding coastal landscape.
Built using landfill timber and steel, the entire installation is engineered to be easily demounted and its components reused after the tunnel’s completion. Such temporary interventions often spark conversations akin to studying historical architecture and its enduring structural life cycles.
Connecting Regions
Scheduled to open fully by 2029, the Fehmarnbelt Tunnel project will ultimately slash train travel times between Hamburg and Copenhagen to just two and a half hours. Mega-infrastructure undertakings of this caliber regularly reshape regional architecture and transnational transit corridors.
Future Outlook
As public curiosity grows, installations like Pilen demonstrate how modern civil engineering can actively invite community engagement. Observers fascinated by large-scale transformations can also dive into architecture tours to witness similar marvels firsthand.
