99 Oaks is an archaic placename of the Santa Clarita Valley, Los Angeles County, California in the United States.^[1] The location was mainly a rest stop between Castaic and Castaic Junction in what was then a fairly remote location along Old Highway 99.^[2] Otis and Macy Andrews opened the 99 Oaks Café in 1936.^[3] Circa 1950, 99 Oaks had a service station and a café.^[4] The name 99 Oaks was later used for buildings nearby, such as 99 Oaks Auto Court in Mint Canyon,^[5] 99 Oaks Cabins in Castaic,^[6] and the 99 Oaks Car Lot in Newhall.^[7] What little there was of 99 Oaks "mostly disappeared" when Route 99 was replaced by Interstate 5 in 1968.^[8]
