Appin Road is a New South Wales secondary highway linking Campbelltown and the Sydney's western suburbs with Wollongong. It gets its name from Appin, which lies on its path and is the southern half of the State Route 69. State Route 69 begins where Metroad 9 ends on the Narellan Road/Hume Highway interchange and continues until the Southern Freeway (leading to Wollongong) interchange at Bulli Tops passing through Campbelltown and Appin along the way. It is dual-carriageway in Campbelltown and southwards, plenty of overtaking lanes thereafter.
