Innovative circular material-hybrid bridge construction
Project
The Illersteg pedestrian bridge, designed to span 70 meters across the Iller River in Kempten, Germany adheres to the principles of the circular economy. The structure consists of prefabricated modular wooden segments, an efficient load-bearing steel structure, and a thin layer of carbon fiber-reinforced concrete as the bridge deck. The structure strategically utilizes its three key materials – steel, wood, and carbon reinforced concrete – according to their functional and performance characteristics. These materials are combined in such a way that facilitates maintenance, replacement, and recyclability at the end of the bridge’s life cycle.
