State Route 164 (SR 164) is a 14.82-mile-long (23.85 km) state highway serving southern King County in the U.S. state of Washington. The highway, which connects Auburn and Enumclaw along the White River, begins at an interchange with SR 18 in Auburn and travels southeast to Enumclaw, where it intersects SR 169 and ends at SR 410. SR 164 serves as an alternate route towards Buckley and Chinook Pass, via SR 410, and also passes the Muckleshoot Indian Reservation.
SR 164 was originally part of various state wagon roads between 1913 and 1923, becoming part of State Road 5, later Primary State Highway 5 (PSH 5), and U.S. Route 410 (US 410) in 1926. US 410 was later realigned south in the 1940s and SR 167 was assigned to the former route during the 1964 highway renumbering. In 1969, SR 164 was established and the western terminus was later shortened to an interchange with SR 18 south of Auburn.
