Bakersfield's population is approximately 365,000, making it the ninth-most populous city in California and the 52nd-most populous city in the nation.  The Bakersfield–Delano Metropolitan Statistical Area, which includes all of Kern County, had a 2010 census population of 839,631, making it the 62nd largest metropolitan area in the United States.

The highway travels north from Interstate 705 (I-705) in Tacoma to SR 99 south of downtown Seattle.  It serves cities along the Puget Sound and west of Seattle–Tacoma International Airport in south King County, including Federal Way, Des Moines, and Burien.  SR 509 is part of the National Highway System and is a limited-access highway near the Port of Tacoma and from Burien to its northern terminus in Seattle.  Prior to the 1964 highway renumbering, the highway was part of Secondary State Highway 1V (SSH 1V) from Tacoma to Des Moines and SSH 1K from Des Moines to Seattle.  SR 509 was re-aligned onto the Burien Freeway in 1968 and the Port of Tacoma bypass in 1997, coinciding with the opening of its interchange with I-705 and the cable-stayed 21st Street Bridge.  Various proposals since 1988 have recommended building a freeway extension of SR 509 within the city of SeaTac, connecting the Burien Freeway to I-5, that remains unbuilt. <SEP> State Route 184 (SR 184) is a state route in Kern County, California, locally known as “Weedpatch Highway.”  It is mainly a 2-lane conventional highway, expanding to four lanes in Bakersfield, and Lamont.
