Washington State Route 164
State highway in King County, Washington, US
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.
Route description
SR 164 begins as Auburn Way at a partial cloverleaf interchange with the SR 18 freeway south of the Auburn Shopping Center in Downtown Auburn. The highway travels southeast and passes Les Gove Park and White River Valley Museum before leaving Auburn, following the White River upstream into the Muckleshoot Indian Reservation, passing the Muckleshoot Casino. Auburn Way travels east and southeast within the reservation, passing Seattle Air Route Traffic Control Center, the Auburn Adventist Academy and Muckleshoot Tribal School. SR 164 leaves the reservation and enters rural King County, continuing to follow the White River as the Auburn–Enumclaw Road and passing the White River Amphitheatre, turning east as it approaches Enumclaw.

Why this record matters
The phrase “state highway in King County, Washington, US” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Dec 15, 2025. The linked authority identifier is Q835665. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1913, 1923, 1926 and 1964.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
