The Buttonwillow CHP Area was created in 1992 to better service the Interstate 5 corridor and the communities in the western portion of Kern County. The Buttonwillow Area is responsible for approximately 3,200 square miles of Western Kern County, which is approximately 20 percent of Kern County roadways. We patrol just over 60 miles of Interstate 5 from the Kern/Kings County Line to State Route 166. We also patrol several hundred miles of unincorporated county roads in western Kern County, including the communities of Buttonwillow and Lost Hills, State Routes 46, 58, 43, 119, 166 and 33. Our Area includes both flat desert and mountainous areas. Interstate 5 brings a great deal of traffic through our Area and many commuters utilize our surface streets during their commute to the oilfields on the west side of the county.
