State Route 515 (SR 515) is a 7.86-mile-long (12.65 km) state highway in the U.S. state of Washington serving King County. The highway travels north from SR 516 east of Kent to Renton, intersecting Interstate 405 (I-405) and ending at SR 900. Originally signed as Secondary State Highway 5C (SSH 5C) in 1937, the highway was established during the 1964 highway renumbering and expanded to its current four-lane width in the 1960s.
SR 515 begins as 104th Avenue at an intersection with SR 516 east of Kent and Kent-Meridian High School. The four-lane highway travels north, parallel to the SR 167 freeway, into the census-designated place of East Hill-Meridian on 108th Avenue and passes Panther Lake. SR 515 turns northwest into Renton on Benson Drive and Talbot Road and descends from Talbot Hill, intersecting I-405 in an incomplete diamond interchange. In Downtown Renton, the highway travels northeast on Grady Way and north on Martin Avenue, paralleling I-405, before crossing a BNSF Railway line on Houser Way and ending at an intersection with 3rd Street, signed as SR 900.
