General Information:
The Kwinana and Mitchell Freeways are without a doubt one of the most important road systems in the Perth metropolitan area, and the southwestern part of the state.
Running in a north-south direction, the freeways link the north and southern suburbs of Perth together, but also act as a coastal link between the northern and southern parts of the state. Built in stages from the late 1950s the route has seen enormous changes / extensions and is still undergoing massive expansion to this day.
Unique to these 2 freeways is the passenger railway line down the median of the freeway, which in parts also travels alongside other modes of public transport such as buses.
The freeway varies from 2 to 3 lanes wide in each direction, with provision in most of the newer sections to have another 1 to 2 lanes to be added when required. Exits along the route are somewhat close together, this is probably due to the large number of suburbs state route 2 services.
When first planned, the Mitchell Fwy was called the Yanchep Highway, as its envisaged that eventually the route will connect to the town.
State Route 2 is joined by National Route 1 at Brentwood from the Leach Hwy (SR7) interchange, forming a duplex through to the Canning Hwy (SR6) interchange at Como.

The Kwinana Freeway Extension, together with the Peel Deviation, will provide a continuous dual carriageway from Perth to the South West. The 70 km of new road will extend the dual carriageway from Kwinana Freeway at Safety Bay Road, around the eastern side of the Peel Inlet and Harvey Estuary to join the existing dual carriageway on the Old Coast Road near Lake Clifton. The New Perth Bunbury Highway will be constructed to a freeway standard from Safety Bay Road to Pinjarra Road with the remainder of the route being built as a rural highway. In the future as traffic demands increase, the highway will be upgraded to a freeway standard for its entire length. *****
