Major roads in rural Western Australia connect regional and remote centres of Western Australia, forming the basis of the road network outside of Metropolitan Perth. Main Roads Western Australia controls and maintains these roads and highways. [1] Some of these roads, or portions of them, are designated and signposted as part of a road route, as they are of national or regional importance. [2] [3] Additionally, roads through areas of scenic or historic significance are designated as part of a Tourist Drive. [2] Each route has a unique marker: National Highways have gold numbers on a green shield, National Routes have black numbers on a white shield, State Routes have white numbers on a blue shield, Tourist Drives have white numbers on a brown shield.

The National Highway is a system of roads connecting all mainland states and territories of Australia, and is the major network of highways and motorways connecting Australia's capital cities and major regional centres.
Highways in Australia are generally high capacity roads managed by state and territory government agencies, though Australia's federal government contributes funding for important links between capital cities and major regional centres. Prior to European settlement, the earliest needs for trade and travel were met by narrow bush tracks, used by tribes of Indigenous Australians. The formal construction of roads began in 1788, after the founding of the colony of New South Wales, and a network of three major roads across the colony emerged by the 1820s. Similar road networks were established in the other colonies of Australia. Road construction programs in the early 19th century were generally underfunded, as they were dependent on government budgets, loans, and tolls; while there was a huge increase in road usage, due to the Australian gold rushes. Local government authorities, often known as Road Boards, were therefore established to be primarily responsible for funding and undertaking road construction and maintenance. The early 1900s saw both the increasingly widespread use of motorised transportation, and the creation of state road authorities in each state, between 1913 and 1926. These authorities managed each state's road network, with the main arterial roads controlled and maintained by the state, and other roads remaining the responsibility of local governments. The federal government became involved in road funding in the 1920s, distributing funding to the states. The depression of the 1930s slowed the funding and development of the major road network until the onset on World War II. Supply roads leading to the north of the country were considered vital, resulting in the construction of Barkly, Stuart, and Eyre Highways.
Australia's Highway 1 is a network of highways that circumnavigate the country, joining all state capitals except the national capital of Canberra. At a total length of approximately 14,500 km (9,000 mi) it is the longest national highway in the world, surpassing the Trans-Siberian Highway and the Trans-Canada Highway. Over a million people traverse some part of the highway network every day.
A routenumber, designation or abbreviation is an identifying numeric designation assigned by a highway authority to a particular stretch of roadway to distinguish it from other routes and, in many cases, also to indicate its classification, general geographical location and/or orientation. The numbers chosen may be used solely for internal administrative purposes; however, in most cases they are also displayed on roadside signage and indicated on maps.
Albany Highway links Western Australia's capital city Perth with its oldest settlement, Albany, on the state's south coast. The 405-kilometre-long (252 mi) highway travels through the southern Wheatbelt and Great Southern regions, and is designated State Route 30 for most of its length. Outside of Perth the highway is predominately a sealed, single carriageway with regular overtaking lanes in some undulating areas. Albany Highway commences at The Causeway, a river crossing that connects to Perth's central business district. The highway heads south-east through Perth's metropolitan region, bypassed in part by Shepperton Road and Kenwick Link, and continues south-eastwards through to Albany. It intersects several major roads in Perth, including the Leach, Tonkin, Brookton, and South Western highways. The rural section of Albany Highway connects to important regional roads at the few towns and roadhouses along the route, including Coalfields Highway at Arthur River, Great Southern Highway at Cranbrook, and Muirs Highway at Mount Barker.
Great Northern Highway is an Australian highway that links Western Australia's capital city Perth with its northernmost port, Wyndham. With a length of almost 3,200 kilometres (2,000 mi), it is the longest highway in Australia, with the majority included as part of the Perth Darwin National Highway. The highway is constructed as a sealed, predominantly two-lane single carriageway, but with some single-lane bridges in the Kimberley. The Great Northern Highway travels through remote areas of the state, and is the only sealed road link between the Northern Territory and northern Western Australia. Economically, it provides vital access through the Wheatbelt and Mid West to the resource-rich regions of the Pilbara and Kimberley. In these areas, the key industries of mining, agriculture and pastoral stations, and tourism are all dependent on the highway.
Caves Road is a 111-kilometre-long (69 mi) scenic route in the South West region of Western Australia. It connects western Busselton with Augusta, running along or to the west of the Leeuwin-Naturaliste ridge, and is an alternative route to Bussell Highway. Caves Road is also a major component of the route from Cape Naturaliste to Cape Leeuwin, in what is known as the state's Capes Region.
Tourist Drives in Western Australia are routes through areas of scenic or historic significance, designated by route markers with white numbers on a brown shield. Tourist Drives were introduced into Western Australia while Eric Charlton was the state government Minister for Transport in the 1990s. The 28 numbered routes collectively traverse more than 2,000 kilometres (1,200 mi) across the state. In addition to the Tourist Drives, there are unnumbered routes such as the Golden Pipeline Heritage Trail, and local governments may designate and maintain local scenic drives, generally unnamed and unnumbered.
Highways and main roads in the Wheatbelt region of Western Australia form the basis of a road network, which is primarily used by the mining, agriculture, and tourism industries. Main Roads Western Australia maintains and controls these major roads, with offices based in Northam and Narrogin.
Main Roads Western Australia controls the major roads in the state's Mid West region. There are four main highways through the Mid West: The north-south coastal route of Brand Highway and North West Coastal Highway, the inland alternative Great Northern Highway, and the northern section of Goldfields Highway, which links Meekatharra with Kalgoorlie. A network of main roads connects towns within the Mid West to each other, the highways, and neighbouring regions, with local roads providing additional links and access to smaller townsites. Roads are often named after the towns they connect.
Main Roads Western Australia controls the major roads in the state's Gascoyne region. North West Coastal Highway, a north-south route near the coastline, is the main highway the region. A series of main roads connect coastal towns to the highway, and local roads provide additional links and access to the inland portion of the region. Roads are often named after the towns or areas they connect.
Main Roads Western Australia controls the major roads in the state's Kimberley region. Great Northern Highway is the major road connection through the region, with sealed roads spurring off it to connect to population centres, and unsealed roads offering an alternative route between Derby and Wyndham.
Main Roads Western Australia controls the major roads in the state's Goldfields-Esperance region. While the region is the state's largest, the major roads are restricted to the region's western and southern edges. From the major population centres of Kalgoorlie and Coolgardie, Great Eastern Highway heads west towards Perth via the Wheatbelt ; Coolgardie–Esperance Highway leads south to the port of Esperance via Norseman; and Goldfields Highway proceeds north to Wiluna and then on to the Mid West Region. From Norseman, Eyre Highway takes interstate traffic east across the Nullarbor Plain and into South Australia.
