The document summarizes Santiago Calatrava's inclined arch bridge over the River Loire in Orleans, France. The central arch is inclined inward at 68 degrees and supported by two concrete tripods with three inclined branches each. The tripods represent a hand extending the arch. The 200m main span and 470m total length bridge has an asymmetrical, curved deck resembling a ship's hull with the arch as a mast. Cables in a reversed V-form suspend the bridge to stabilize the arch and distribute force from its inclination.

Editor's Notes
- #5: Calatrava’s dynamic designs integrate technology and aesthetics producing structural forms that challenge traditional practice in both architecture and engineering.He is an organic architect who finds his inspiration in the human body and in nature and, because of his background in both architecture and engineering, he has learned to combine sculptural concepts with technology to create designs that are both visually striking and structurally daring."To me, there are two overriding principles to be found in nature which are most appropriate for building; one is the optimal use of material, the other the capacity of organisms to change shape, to grow, and to move."
