Its reinforced concrete design was an engineering achievement of its day. It also continues to serve as a vehicle and foot link and as a landscaped community feature.","narrative":"Spanning the Santa Fe Railway between Oaklawn and Fair Oaks Avenues in South Pasadena, this 1906 bridge carries vehicles and pedestrians on a graceful concrete arch. It has six spans and runs 340 feet, and the arch is only twelve inches thick at the center. At the east end, a waiting station built of Arroyo Seco boulders with red brick detailing and a heavy timber roof of clay tile once sheltered electric car passengers. The South Pasadena Realty and Improvement Company sponsored the structure. Greene and Greene designed it, Carl Leonardt built it, and Michael de Palo, a pioneer in reinforced concrete, served as consulting engineer. It is the only bridge the architects designed. The railway required an extra pillar in span two, which the architects added reluctantly because they felt it spoiled the grace of the design. Its significance rests on architecture, engineering, landscaping, transportation and urban planning, and it remains a useful link in the community.","period_of_significance":"1906","architect_builder":"Greene and Greene (architects); Carl Leonardt (builder); Michael de Palo (consulting engineer)","architectural_style":"Early Modern (Bridge); Bungalow/Craftsman (Waiting Station)","criteria":[],"status_note":"Described as in good condition, on its original site and unaltered in the 1972 form; owned by the City of South Pasadena and in use as a road crossing.
