 The 285-kilometre-long (177 mi) roadway links Cann River in Victoria to Canberra in the Australian Capital Territory (ACT) via the Monaro region. From its southern terminus, it follows the nearby Cann River upstream towards the New South Wales border through heavily forested terrain. Within New South Wales (NSW), it makes its way through further forest before reaching the pastures typical of the Monaro. There are multiple towns and villages along the highway, including Bombala, Nimmitabel, and Cooma. The terrain within the Monaro is largely hilly, and there are numerous crossings. The road also parallels the former Bombala railway line in several locations. Within the ACT, the road becomes a high volume roadway and serves the southern suburbs of Canberra.
