Constructed in 1913, this bridge was part of the Pacific Electric Railway system. In 1973, the American Society of Civil Engineers, Los Angeles section, designated the system a Local Historic Civil Engineering Landmark. Although the bridge no longer carries rail traffic, it serves as the gateway to the City of Torrance. In the bridge's centennial year, it was recognized as a Local Historic Landmark and was officially named the Pacific Electric Railway El Prado Bridge by resolution of the City of Torrance.
