The competition brief required a design of a pedestrian and bicycle bridge over the river Elliðaá in the newly expanded park of Heiðmörk, on the outskirts of Reykjavik. The proposed concept was to have one single architectural element to provide all the structure and sensorial detail, in this case the baluster, as one single form and to provide one simple function. With the floor of the bridge made of a lightweight concrete slab, which tapers from bottom to top, the flat sheet balusters would project up from the flooring slab and twist 90 degrees, forming the balusters and handrail as one continuous organic flowing element. 

The uniform nature of the Corten steel balusters would add a reassuring elegance and simplicity to the overall form. Atmospheric lighting between each steel member embedded in the bridge's floor washes diffused light up along the steel members of the bridge, blurring the boundaries between baluster and bridge base structure. The scheme utilizes LEDs for all lighting, as the lighting concept in the three-metre-tall street lights and the "Spogot" diameter with ellipse-shaped light curves would distribute light on both sides of the path. Micro hydro-powered turbines power the atmospheric lighting. These are placed on the river bed under the bridge and, with a flow of 50 litres per second, can produce approximately 1,000 watts - sufficient to power the bridge's lighting, making the atmospheric lighting of the bridge self-sustaining.
