The 344-hectares new Mohammed Bin Salman Nonprofit City in the heart of Riyadh shall house two unique pedestrian bridges crossing the pristine Wadi Hanifah. The Forum Bridge links four highlights of the Cluster and connects people through spaces of art and event. The Lighthouse Bridge is designed as a double cable-stay suspension bridge with one central pylon taking the load of the two 200m long spans - a unique design that will set a new landmark along Wadi Hanifah constituiting the entrance of the Cluster like a lighthouse. The Wadi's inlets create a dramatic backdrop for the Cluster, utilised prominently with the Promenade and so creating a vibrant space of public interaction. At strategic locations, the two bridges join the otherwise fragmented areas and thus support the human centered design around the walkable and cycling-prioritized Mohammed Bin Salman Nonprofit City. The Forum Bridge is not only connecting the three sides of the Cluster's Forum District with some of the key assets such as the Science Museum, the MiSK Foundation and Conference Centre and the LIFELINE, it also connects the plateau area at large with all its activities to the Wadi Park at its base. On the walk down or up, visitors will be able to appreciate different views into the Wadi from three viewing platforms, which also will be used for art exhibitions and other temporary functions. The central structure has been formed utilising a parametric model on the theme of erosion mirroring the formation of the Wadi. On a larger scale the Lighthouse Bridge is situated on a strategic axis enabling a pedestrian and cycling connection that will provide connectivity beyond the limits of the Mohammed Bin Salman Nonprofit City.
