I could find no information about the date or exactly location of this photo of the Pacific Coast Highway section of Highway 1 that stretches from Santa Monica through Malibu to Oxnard. What it does look like are the palisades along Santa Monica beach. From the looks of the motorcars, it looks to be the 1930s, and from the long line of vehicle parked along the cliff, I’m going to guess it was a Sunday during the summer.

Daniel says: “The width of the road indicates 1930s. PCH was called Roosevelt Hwy at the time, and would be numbered US 101A in 1936. PCH/CA 1 did come into being until 1964.”

KCET says: Roosevelt Highway began as Route 60. It was later redesignated Route 3, then Route 101 Alternate. It was not until 1964 that the green shields designating PCH as California State Route 1 appeared roadside.
