Safety Bay Road is an east-west metropolitan road located in the City of Rockingham, about 50 kilometres (31 mi) south of Perth, Western Australia. The road starts in Rockingham's coastal suburbs and heads south from Peron past Lake Richmond. The road then turns left at the coast with a roundabout with Arcadia Drive which is a coastal road in Shoalwater. Safety Bay Road takes a left turn and extends past Ennis Avenue and Warnbro railway station to the newer suburban estates at Baldivis, before ending just past the Kwinana Freeway. As such, it forms a key link between Rockingham, Perth and Mandurah. Until 2009, the end of the road marked the start of the Kwinana Freeway.

The Kwinana Freeway is a 72-kilometre (45 mi) freeway in and beyond the southern suburbs of Perth, Western Australia, linking central Perth with Mandurah to the south. It is the central section of State Route 2, which continues north as Mitchell Freeway to Clarkson, and south as Forrest Highway towards Bunbury. A 4-kilometre (2.5 mi) section between Canning and Leach highways is also part of National Route 1. Along its route are interchanges with several major roads, including Roe Highway and Mandjoogoordap Drive. The northern terminus of the Kwinana Freeway is at the Narrows Bridge, which crosses the Swan River, and the southern terminus is at Pinjarra Road, east of Mandurah.
