The new bridge is a unique construction. In Miniatur Wunderland, the steel structure serves as the bridge between Europe and the South American continent. The bridge is fully enclosed by anti-glare glass so that visitors can move between the continents in warehouse blocks D and L without getting cold or wet. Wanderers between the worlds will have a clear view of the canal. Since the floors of the two warehouses are at different heights, the bridge from Block D to Block L is on a slight decline.
Approximately ten years passed between the initial idea to build the bridge, and the first planning stages, to its lift-in. The new bridge construction was included in the original application for the Speicherstadt to be added to the UNESCO list of World Heritage Sites. With its delicate and subdued design, the new bridge meets Hamburg’s landmark protection requirements.
The new bridge was constructed in a facility in Kassel. A heavy transporter then brought it to Hamburg in one piece. To place the bridge between the two warehouses, a mobile crane that weighs 750 tonnes and can be extended up to 58 metres lifted the steel structure 28 metres above Warehouse D to the designated position.
With a weight of around 40 tonnes (36 at lift-in), the bridge rests on twelve deep foundation piles of up to 18 metres in length. It is 25 metres long, roughly 3.3 metres high and is suspended nearly 16 metres above the canal. “Such an exciting and demanding project is extraordinary, even for an architect here in the Speicherstadt historical warehouse district. And it’s also unique. There will probably be no more new bridges because of the Speicherstadt’s status as a World Heritage Site,” says Alexandre Rombourg, project manager in charge of the bridge at HHLA Real Estate.
