| Abstract: |
Pont Schuman is an elegant new crossing of the River Saône in Lyon, France. The scheme, with an overall cost of around €20Million, was developed as part of an international design competition. The bridge carries a two lane dual carriageway and features a shallow concrete deck suspended from slender un-braced arches. Triangular in cross section, the arches are particularly striking in that they are twisted continuously along their length. This requires two of the main plates that form the arches to be warped, leading to significant challenges in design and fabrication. A unique erection method was used in which the arches were temporarily hinged at their springing points to enable the spans to be transported via a barge from a preassembly area along the Saône under a number of existing crossings. |
