| Abstract: |
Riyadh is under a complete transformation of the transportation network, to meet the needs of one of the fastest growing populations (8% annually over the past 40 years). The purpose of the project is to convert an arterial road into a freeway, requiring three-level interchanges at all main intersections, and to enhance the visual aspects of the urban design. The soul of the Project is the concept of the “dune”, to support a singular vision of the streets- landscaping project, reflected in the morphology of this singular bridge, creating a representative image of the current transformation works. The bridge structure adjusts and corrects the theoretical bending moment curve; and by softening the peaks, it adapts forms that recall the geometries built by the wind in the sand. This dune concept is not only reflected in the main bridge structure, but also in pedestrian walkways, side-medians and pedestrian friendly areas. The bridge was designed based on wave and dune shapes, while fulfilling structural requirements. Besides, lighting, textures, finishing, and colors have been carefully studied to become iconic. The result is a singular and representative bridge that gives character and identity to the area, contributing to build the image of the city. |
