recycle reuse reduce


reuse of the existing highway-bridge
the structural body of the existing highway-bridge is still strong, which is why it should be reused instead of being demolished. compared to building a new bridge with the same requirements this means a reduction of 30% of costs and – even more important – 45% of emissions which is about 500 tons of CO2. furthermore, this is a globally unique chance for a statement on future developments.

an analysis of the existing structure shows low utilization of some parts. these are cut along a defined curve. thanks to this reduction of weight, it is the ideal fit as a new base body for the cycling bridge.  at the same time, a new and exciting shape is created. combined with friendly appearance and a dash of strong color this gives a fresh identity and make reuse an important topic of discussion. additionally, it proves that reused building parts do not need to feel dusty or old.


new experiences through deceleration
the curved path adheres to the new shape. not only does it connect the two river banks, but it also slows down the traffic. this way the bridge becomes a place of welcome change and space for calming down along the major cycle-route. this path is continued with the ramps on both sides which makes the bridge both more interesting and also increases the safety for all visitors.

modular, highly flexible and playful furniture adds even more reasons to enjoy lingering on the bridge. thus, together with the curved shape various areas to stay with rich offerings are created. ranging from simple furniture like benches, picknick tables and reclined surfaces all the way to unique amenities like trampolines built into the surface, nets for padlocks and peepholes. the chosen coverings – concrete with a broom finish as the cycle-path, soft rubber granulates as the pedestrian path and the lingering areas – divide and differentiate the river crossing. the generous staircase seatings on both banks serve as an additional offering. their positioning unravels the paths of pedestrians and cyclists.
