Paolo Soleri may be best-known for his ongoing Arcosanti project, but the architect first gained widespread attention in 1949 for a bridge design displayed at the Museum of Modern Art. He’s conceived many spans since then, but not one has been built. That changes in December, when a Scottsdale, Ariz., structure for pedestrians opens. Bridges: Spanning the Ideas of Paolo Soleri—organized by Scottsdale Public Art, which commissioned the footbridge, and the Scottsdale Museum of Contemporary Artoffers a unique look at the architect, surveying six decades’ worth of Soleri’s visions for the structures that connect people and communities.
