Rintala Eggertsson Architects won the competition with a steel lattice bridge in cor-ten steel and wooden floors, walls and ceilings in wood. It was an important for the client to provide the pedestrians with enough visibility to the powerful nature in the area. The river is also a good fishing river, which has proved to be a source of recreation for the local population where the old bridge was an important a basecamp of activities.
The design of the new bridge was generated by the idea of a rhythmical play of modules crossing the river in order to break down the timeline into intervals and reduce the monotony when crossing the river. This play of modules would be based on the distance between the already existing pillars in the river, the only remains of the old bridge. The main steel structure would form the base rhythm and the wooden structure a secondary movement, similar to what you would find in a score for percussion instruments.
The two rooms on top of the pillars were therefore used to generate pauses in this otherwise regular rhythm, offering a break from the linear movement across and a possibility of more direct contact with the landscape. They were also ideal as fishing platforms as the two activities would not need to disturb each other anymore.
As it often is the case with bridges, maintenance was an important issue for the client. They were therefore very intrigued by the idea of using Cor-ten steel as a main structure and Accoya as a cladding material. That would combine strength, durability and above all no costs of maintenance over the years. They also liked the idea of covering the bridge with a roof, which would eliminate the need of snow plowing, which can be complicated issue for pedestrian bridges.
