From Busselton, it starts as State Route 104 from the Bussell Highway 3 km east of Busselton, near the Sir Stuart Bovell sporting complex, and travels the 56 km to Nannup, where it intersects with the Brockman Highway and becomes State Route 10. It then passes Donnelly River and Karri Valley Resort, and 22 km west of Pemberton turnoffs provide entrances to the Beedelup National Park.^[2]
