Sherman Pass is Washington’s highest maintained road
Sherman Pass is a high mountain pass at an elevation of 1.684m (5,524ft) above the sea level, located in Ferry County, in the U.S. state of Washington. It is the highest pass in the state maintained all year.
Located within the Colville National Forest, the road to the summit is totally paved, but steep in parts. It’s called State Route 20 (Sherman Pass Scenic Byway). The pass was named after American Civil War general William Tecumseh Sherman.
The pass is 59km (36.7 miles) long. It begins near the town of Republic on WA-21, and runs east to the town of Kettle Falls, on US-395. The drive is highly recommended from late spring to early fall.
