South Western Highway is a highway in the South West region of Western Australia connecting Perth's southeast with Walpole. It is a part of the Highway 1 network for most of its length.[1] It is about 406 kilometres (252 mi) long.

Route description

Perth to Bunbury

From Perth, the highway, signed as State Route 20,[1] starts from the Albany Highway junction in Armadale, 28 km from Perth, and follows a north–south route 20–30 km inland from the coast, passing through several agricultural and timber towns that sprang up in the 1890s when the nearby railway came through, such as Pinjarra, Waroona, Yarloop and Harvey.

In January 2016, the Samson Brook bridge, one of the highway bridges near Waroona, was damaged by a bushfire.[2]

.

In Bunbury

The highway does not actually enter Bunbury – it stops at the industrial suburb of Picton, following Robertson Drive (Bunbury's ring road) for 1 km south before turning southeast past Bunbury Airport towards Boyanup. The highway actually used to follow what is now Boyanup-Picton Road from Picton via Dardanup, but changed to the present shorter route in the 1980s.

Bunbury to Walpole

From Bunbury, the highway goes through Boyanup and on to

karri. The region was settled much later than other parts of south western WA, under a soldier resettlement scheme
beginning in 1919. Typical scenery is farmland interspersed with forests and small timber towns.

The highway then goes through

From Walpole, the Highway 1 continues as South Coast Highway to Albany.

History

Following the establishment of the Swan River Colony, the earliest report of exploration of the district around what is now Bunbury is from Lieutenant H. W. Bunbury in December 1836. The route he – and later others – took was slow and hazardous, taking four days to cover around 80 miles (130 km), and crossing four rivers. The route began with passage from Perth to Pinjarra, before turning south-west and passing through low, open scrubland, and subsequently a medium-timbered area with low marshes. The first river to cross was the Harvey River, which could only be forded by horses at a single point, near the river mouth. Continuing south-westward, the northern tip of Leschenault Estuary was reached, and its shores followed before curving around into Bunbury. The last stretch of approximately 12 miles (19 km) was the most dangerous for many years, as it required precarious crossings at the Collie and Preston Rivers.[3]: 1–2 

In an initial attempt to settle the area, the government declared the land open for pastoral settlement by ordinary settlers, but little progress was made. By 1840, the population was just fifty-three, and most of those were in or near Bunbury (then known as Port Leschenault).

Western Australian Land Company in 1840–41 prompted the first real need for a good quality road to Perth.[3]: 4 [4] Throughout much of 1842, there was much debate and discussion over providing a new route to Bunbury. A coastal route from Fremantle had been proposed, while an alternative proposal published on 11 May 1842 was a new route from Pinjarra to Bunbury, via an upstream crossing of the Harvey River, where a bridge could easily be built.[5] The coastal route would require a ferry to cross the Murray River's estuary,[a] and did not go through Pinjarra, a significant settlement in the area; however, it would be shorter, had more water along the route, and did go through the village of Mandurah, with a population of twenty-nine people from six families.[3]
: 5–6  During the winter of 1842, the existing route became impassable, and Clifton decided to undertake the creation of the proposed coastal route. He sent his company's men to clear the path and make a road.[3]: 8–9 

By the second half of the nineteenth century, the importance of the coast road was diminishing.[3]: 15  For most of its length, the road went through well-timbered, sandy limestone country of little value to agriculture, and settlers in the vicinity of the road were scarce.[6] In contrast, settlements had spread and prospered in the foothills of the Darling Scarp, and on 1 July 1853, Colonial Secretary Frederick Barlee announced a new proposal for a Perth–Pinjarra–Bunbury route along the foothills, with a one chain (66 ft; 20 m) width, mostly following the alignment of previous tracks. Between 1864 and 1876, two parties of convicts were involved in the making of the road.[3]

A road from Bunbury to Boyanup, called the Blackwood Road, existed as early as 1864.[7][8] A bi-weekly mail route from Boyanup to Bridgetown via Preston, Balingup, and Greenbushes was established by 1891; it also extended further south to Balbarrup on a weekly basis.[9] Surveying of a direct Bridgetown–Albany route was requested in January 1871, so that an electric telegraph line could be established, but the government surveyors were overwhelmed by other work.[10] Surveying of the route from Manjimup (south of Bridgetown, adjacent to Balbarrup) was undertaken in 1909 by Fred S. Brockman.[11]

Following World War I, the government intended to settle returning servicemen in the far south-west of the state. To determine the public works required, a flying survey was undertaken. The route between Manjimup and Walpole (then known as Nornalup) was reported to be overgrown and impassable. The Public Works Department was tasked with clearing the route and forming a road, with works gradually progressing from c. 1919 onwards. By October 1921, £16,000 had been spent on upgrading the dirt track to a formed and gravelled road, with works expected to be completed over the 1921–22 summer at a cost of £2,000.[12]

The road from Bunbury through Bridgetown to Manjimup was improved in 1926, as one of the Main Road Board's first projects. The worst segments were identified for reconstruction, as part of an ongoing process to create a high-quality highway.[13]

The name South Western Highway was suggested for the road from Armadale to Pemberton in 1940 by the Under-Secretary for Lands.[14] The name was in common usage by March 1941,[15][16] and in July 1941, the name was officially applied to "the main road from Armadale to Pemberton via Pinjarra, Harvey, Picton Junction, Boyanup, Donnybrook, Bridgetown and Manjimup".[17] The northern end was at the Perth–Albany road[b] in Armadale, and the southern end was at Brockman Street, Pemberton.[17]
