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).

Located entirely in Cache County, SR-101 starts at an intersection of Main Street and SR-23 (Center Street) in Wellsville. The highway heads easterly for the first before it turns northeasterly, crossing the Little Bear River and intersects US-89/US-91 at a traffic light controlled at-grade interchange. After the interchange, SR-101 turns to the southeast after entering Hyrum city limits. At 400 West, SR-101 turns south for 3 blocks before turning back to the east, and intersecting SR-165.
