Washington State Route 168
highway in Washington
State Route 168 (SR 168) is a legislated, but not constructed, state highway located in Washington, United States. The highway is meant to serve as an alternate crossing through the Cascade Range at Naches Pass, supplementing the seasonal Chinook Pass on SR 410. Proposals were first drawn in the 1930s, and the highway has been codified in law under its current designation since 1970, but no construction has occurred.
Route description
The highway is legislated to begin at a junction with SR 410 in Greenwater, in eastern Pierce County. The road would travel east along the historic Naches Trail, passing through Mount Baker-Snoqualmie National Forest and across Naches Pass to Wenatchee National Forest. It would terminate at another junction with SR 410 north of Cliffdell in Yakima County. The highway would pass near Pyramid Peak, which has a maximum altitude of 5,718 ft (1,743 m). A crossing similar to the legislated highway is covered by a series of Forest Routes, including Road 19 and Road 70.
SR 168 would be an all-season route through Naches Pass, at an elevation of 4,923 feet (1,501 m), providing an alternative to SR 410, which closes annually due to avalanche dangers near Chinook Pass, at an elevation of 5,430 feet (1,655 m). SR 168 would allow commercial vehicles to bypass Mount Rainier National Park, where trucks and other large vehicles are prohibited on SR 410.

Why this record matters
The subject matters to the general reference register because the source frames it as highway in Washington. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 5, 2025.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.
