U.S. Route 101
U.S. Route 101, or U.S. Highway 101 (US 101) is a north–south United States Numbered Highway that runs through the states of California, Oregon, and Washington, on the West Coast of the United States. It is also known as (The Royal Road) where its route along the southern and central California coast approximates the old trail which linked the Spanish missions, pueblos, and presidios. It merges at some points with California State Route 1 (SR 1).

Arriving in Humboldt County, another narrow two lane portion of US 101 bisects Richardson Grove State Park. Just after the park boundary, the highway switches to a short undivided freeway and then eventually a divided freeway just before reaching Garberville. North of Garberville, US 101 reverts to an undivided freeway, which continuing north by northwest, passes through the Humboldt Redwoods State Park, California's third largest State Park and the site of the largest remaining Redwood old growth forest in the world. A preserved portion of the original, bypassed highway route, known as the Avenue of the Giants for the huge, centuries-old redwood trees, parallels the highway for over in southern Humboldt County. US 101 again switches to another stretch of divided freeway near the town Pepperwood before reverting to a short, 2-mile (3 km) expressway just north of Stafford. A short freeway then runs through Rio Dell before another short, 3-mile (5 km) expressway.
