The M420 continues through Cranbourne and Koo Wee Rup until the Bass Highway turnoff, which is then designated A440 onwards to Sale. From the Bass Highway junction, the highway is undivided. The South Gippsland Highway is the gateway from Melbourne to many attractions including Wilsons Promontory and Phillip Island as well as being an important road for farmers in Gippsland.
