When the current state highway numbering system was first posted in January 1964, SR 167 began at Jct US 410 in Enumclaw and headed NW to Auburn, then north via Kent and Renton to Jct SR 900 in Seattle's Rainier Valley. In 1970, the Enumclaw to Auburn portion of SR 167 was renumbered SR 164 . SR 163 from Sumner to Auburn and SR 410 from Tacoma via Puyallup to Sumner became part of SR 167. Effective April 1, 1992, SR 167 north of SR 900 in Renton to Seattle was dropped from the state highway system. Today, SR 167 is 28.60 miles long.
Before 1964, SR 167 was part of PSH 5.
In the future, the Tacoma to North Puyallup section of SR 167 will be replaced by a new SR 167 freeway from Jct SR 509 in Fife to North Puyallup.
