Architecture, Building and Structure Design Esfahan Knowledge Bridge by Kalbod Studio Esfahan is a pedestrian bridge designed for a site in Isfahan, Iran. The bridge links a technology trade center with a museum garden and serves nearby universities, research institutes and industries. Exhibition halls, central courtyards and resting areas are placed along the route, so the crossing also works as a public space. The form refers to the historic bridges of Isfahan, including the Khajoo bridge. Reflective symmetry is used, so the facade and its image on the river form one complete pattern. The interior spaces are flexible and can host different uses.
