The extension of Roe Highway from its current terminus at Kwinana Freeway to Stock Road will complete a key link in Perth’s south western metropolitan area road network.

Roe Highway Extension will be a significant east–west linkage in the southern metropolitan area, supporting demand for between 45,000 and 75,000 vehicles per day by 2031.

Stock Road is ultimately planned to be constructed to freeway standard with grade separated interchanges. This further supports the use of Roe Highway and Stock Road as the preferred route to the Fremantle Inner Harbour (via Stock Road, Leach Highway and High Street), the Kwinana Industrial Area (including the proposed Latitude 32 freight hub and the Australian Marine Complex), and the proposed Outer Harbour.

The reservation for Roe Highway extends further west than Stock Road and it is likely that a road of some type will need to be constructed in this reserve to provide improved access to the coastal area south of Fremantle, which includes the proposed Cockburn Coast development. There is however no urgency to construct this section and current planning studies will identify the likely type and timing of the road (refer to the table below).

Several planning studies are in progress to evaluate the requirements for Perth’s rapidly expanding south west corridor. These studies include:
