A joint team from an architectural practice and an engineering company has won a competition to design a set of three bridges in timber, stone and steel for a development in Norway.

UK practice Moxon Architects and COWI, a Danish engineering consultancy, came together to produce three designs for bridges over the Lysaker river in Oslo for developer Mustad Einedom.

Two of the bridges, known as the Kulturbroene, are pedestrian bridges connecting the development’s cultural hubs. The third bridge is a cycle bridge.

The 40m northernmost pedestrian bridge is a straight timber span with landings at varying heights. Timber was chosen as a building material to reduce weight, foundation requirements, and environmental impact.

The southernmost pedestrian bridge is built from regionally sourced stone blocks strung together to form shallow arching beams. It is designed to withstand heavy pedestrian and vehicle traffic and seasonal floods.

The cycle bridge has an S-shaped trajectory, providing an accessible gradient to connect two banks with a height difference of more than 4m.
