Albany Highway links Western Australia's capital city Perth with its oldest settlement, Albany, on the state's south coast. The 405-kilometre-long (252 mi) highway travels through the southern Wheatbelt and Great Southern regions, and is designated State Route 30 for most of its length. Outside of Perth the highway is predominately a sealed, single carriageway with regular overtaking lanes in some undulating areas. Albany Highway commences at The Causeway, a river crossing that connects to Perth's central business district. The highway heads south-east through Perth's metropolitan region, bypassed in part by Shepperton Road and Kenwick Link, and continues south-eastwards through to Albany. It intersects several major roads in Perth, including the Leach, Tonkin, Brookton, and South Western
