1915 construction, the Standard-to-Richfield evolution, and 56 years of operation
The 1915 construction date places the Cucamonga Service Station among the very earliest purpose-built American gas stations — the dedicated-building service-station form was less than a decade old when this station opened, and the design at 9670 Foothill Boulevard reflects the experimentation that was still occurring in the form's early years. Standard Oil of California (the corporate predecessor to Chevron and Richfield) built the station as part of a wave of new locations responding to the rapid growth of car ownership in Southern California — the state had approximately 50,000 registered automobiles in 1910, more than 200,000 by 1920, and more than 1.5 million by 1930.
The Standard-to-Richfield branding evolution reflected the corporate restructuring of the petroleum industry in the 1920s and 1930s. Richfield Oil Corporation was a Southern California-focused subsidiary that operated under the distinctive eagle-and-shield logo through several decades; the corporate name eventually merged with Atlantic Refining in 1966 to form Atlantic Richfield (ARCO), the contemporary brand. The Cucamonga station operated under all three names during its 1915-1971 operational life and preserves signage and ephemera from each branding era.
The 56-year continuous operation from 1915 through 1971 covered the entire boom period of American automotive culture — the original 1910s and 1920s emergence of mass car ownership, the Depression-era struggle when many stations closed, the wartime fuel rationing that suppressed civilian gasoline sales, the postwar boom decades when the Route 66 corridor reached its peak commercial significance, and the gradual decline that followed Interstate 10's opening through the area in the early 1960s. The station's final 1971 closure came at a low point in Route 66's history when many similar stations were closing across the corridor.
