Sherman Pass Scenic Byway (WA-20 East)

The eastern segment of WA-20 runs 88 miles from Republic east over Sherman Pass (5,575 ft) — Washington's highest year-round maintained highway — through the Colville National Forest to Kettle Falls on the Columbia. This stretch is fully distinct from the North Cascades Highway (WA-20 west); the two segments do not directly connect. Designated the Sherman Pass Scenic Byway, the road features steep but paved grades, minimal traffic, and dense Colville National Forest scenery. An interpretive site at the summit provides wildfire history context for the 1988 White Mountain Fire that shaped the surrounding forest.
