This section of Pacific Coast Highway was formally dedicated as the 'Theodore Roosevelt Highway' when it was completed in 1929 and was generally known as the 'Roosevelt Highway' or 'Coast Highway' in the 1930s. It was designated as US 101A (Alternate) in 1936. State legislative action in 1964 changed many highway numbers in California, and US 101A became CA 1. In the same year, the state legislature offically named CA 1 'Pacific Coast Highway' in Orange, Los Angeles and Ventura Counties. Photograph caption dated February 2, 1940 reads, "Mud washed down by rain waters today impeded traffic on the Roosevelt Highway north of Santa Monica. Photo shows the highway at Sunset boulevard, with erosion of road shoulder in the foreground. The road is coated with mud."
