Architecture Puzzler #323
The new pedestrian bridge "Passerelle Simone de Beauvoir" crosses the Seine in Paris. It has a length of 885 feet (270 meters) and a main span of 620 feet (190 meters), yet its main structure, a "pectinate lenticular" truss, allows the bridge to be relatively light. Describe the basic "look" of the bridge.
