An exemplar of sustainable infrastructure
Balingen Footbridge
Designed in collaboration with specialist timber engineers Ingenieurbüro Miebach, the pared back structure is in keeping with the natural river setting. The crossing features a pair of outward leaning timber beams, that splay apart as they reach each riverbank enabling fully accessible approaches from all directions. These extend above the level of the deck to form the bridge’s parapets, while allowing it to clear predicted flood levels. The visible, outer faces of the shaped glulam beams are designed to weather naturally over time, while the inner, pedestrian facing surfaces are clad in tactile, native timber slats with carefully integrated lighting and handrails.
‘Balingen Footbridge demonstrates not just the aesthetic and structural potential of timber in place of steel in bridge-building, but the carbon that can be sequestered. Through offsetting the concrete going into the abutments, timber allows you to create a more sustainable piece of infrastructure, that, with the correct maintenance, can last as long as any steel structure’
Bridge Design Awards Citation
Illustrating the aesthetic and structural benefits of timber in place of steel in public infrastructure, and the carbon that can be sequestered, the footbridge embodies Balingen’s dual commitment to sustainability and design excellence.
‘Thanks to the excellent exchange with the architects, we were able to give the simple structural form of a trough bridge a unique typology. We were able to implement our premise for good structural wood protection in an appealing way through the inclined girders. This shows that together we can interpret wood in a contemporary way for bridges, and hope to herald a paradigm shift.’
