The highway was originally built by the county government in the 1910s as a winding gravel road connecting local coal mines. It was straightened and paved in the 1920s and was designated as Secondary State Highway 5C (SSH 5C) in 1937. SSH 5C was replaced by SR 515 in the 1964 state highway renumbering and extended north into downtown Renton after the construction of I-405. A section of the highway on Talbot Highway was moved to a new bypass road in 1982 and other sections in Kent were widened to four lanes in 1991. The I-405 underpass was rebuilt as a half diamond interchange in 2010.
