Significance: The Prospect Boulevard Bridge is the visual link between the neighborhoods of Prospect Park and Arroyo Park. It maintains a suburban scale due to its narrow width, the thinness of its pier supports and the curve of the roadway. It is an example of the early use of reinforced concrete in viaduct construction in southern California. Because the surface of the bridge has been so altered, its primary significance lies in its compatibility to the surrounding historic residential districts in terms of its scale. At the time of its construction, it was the only one of its type built on such a curve.
