About Forrest Highway in brief

Summary Forrest HighwayForrest Highway is a 95-kilometre-long highway in Western Australia’s Peel and South West regions. It extends Perth’s Kwinana Freeway from east of Mandurah down to Bunbury. Old Coast Road, and the Australind Bypass around Australind and Eaton, were subsumed by Forrest Highway. The highway has two lanes in each direction separated by a wide median strip, and a speed limit of 110 kilometres per hour. There are a number of at-grade intersections with minor roads in the shires of Murray, Waroona, and Harvey including Greenlands Road and Old Bunbury Road, both of which connect to South Western Highway near Pinjarra. Forrest Highway is the southern section of State Route 2, continuing south from KwinANA Freeway at a folded diamond interchange withPinjarra Road. The road travels south for six kilometres, over the Murray River and through rural farmland in and beyond South Yunderup. It then veers south-west, meeting Greenlands road at a pair of staggered T-junctions, and continues towards the Harvey Estuary over a distance of nine kilometres before intersecting Mills Road, at another pair of closely spaced T junctions. It continues south for 25 kilometres, to the northern edge of Myalup State Forest and east of Lake Clifton, an alternative coastal route toMandurah. In June 2014, Forrest Highway was extended south to Bunburbury by renaming much of Old Coast road as well as Australind bypass as part of the highway.

It ends at Bunbury’s Eelup Roundabout after ten kilometres. The highway is controlled and maintained by Main Roads Western Australia, and has a two-lane, two-carriageway design with a speed of 110km/h. It was opened on 20 September 2009, and is the final extension of the Kwinane Freeway to the Bunbury area of Western Australia. It is the only highway in the state to have a dual carriageways option. The state government has been upgrading the main Perth to Bun Burbury route, by extending Kwinano Freeway south from Perth, and constructing a dual-carrier highway on Old Coast. A bypass was also planned around Mandurahs, which underwent detailed environmental reviews and assessments in the 1990s and early 2000s. The bypass was completed in June 2014. The new highway was opened in September 2009. It has two at-grade intersections, with cross roads intersected via two closely spaced T- junctions. In these sections, the highway passes the edge of Leschenault State Forest, Preston Beach, Binningup and Binning up. It crosses the Collie River for five and a half kilometres, and five kilometres southwards towards the Collies River. It heads south-east, going inland to the inland bypass of Leshault Inlet. It also crosses the Peel Inlet for five kilometres, going south- east, and half a half kilometres towards the Brunswick River.
