| Abstract: |
The aim of this paper is to present the conceptual design process of the proposed Extradosed Bridge, as part of the Third Ring Road of Mecca project, near the Jamarat site in KSA. The proposed bridge is conceived as an Extradosed Bridge with an open cross section with two main longitudinal girders in post tensioned concrete and spans of 85-145-90 m. It is the result of a conscious and rigorous conceptual design process, that took into consideration the special context and boundary conditions, in some cases, quite unusual for a road bridge. The resulting slender, durable, and elegant bridge fits in the context, providing an iconic, yet subtle reference to this important site. |
