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, which travels through remote areas of the state, is constructed as a sealed, predominantly two-lane single carriageway, but with some single-lane bridges in the Kimberley.

In these areas, the key industries of mining, agriculture and pastoral stations, and tourism are all dependent on the highway.
Great Eastern Highway is a 590-kilometre-long (370 mi) road that links the Western Australian capital of Perth with the city of Kalgoorlie. A key route for road vehicles accessing the eastern Wheatbelt and the Goldfields, it is the western portion of the main road link between Perth and the eastern states of Australia. The highway forms the majority of National Highway 94, although the alignment through the Perth suburbs of Guildford and Midland, and the eastern section between Coolgardie and Kalgoorlie are not included. Various segments form parts of other road routes, including National Route 1, Alternative National Route 94, and State Route 51.

Forrest Highway is a 95-kilometre-long (59 mi) highway in Western Australia's Peel and South West regions, extending Perth's Kwinana Freeway from east of Mandurah down to Bunbury. Old Coast Road was the original Mandurah–Bunbury route, dating back to the 1840s. Part of that road, and the Australind Bypass around Australind and Eaton, were subsumed by Forrest Highway. The highway begins at Kwinana Freeway's southern terminus in Ravenswood, continues around the Peel Inlet to Lake Clifton, and heads south to finish at Bunbury's Eelup Roundabout. 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.
Indian Ocean Drive is a coastal highway in the Australian state of Western Australia which services the coastal communities along the Indian Ocean immediately north of the state capital Perth, linking the northern suburb of Yanchep with the Brand Highway, just south of Dongara. In terms of regions, most of it exists in the Wheatbelt coastal region. The road provides travellers between Perth and Geraldton a 30-minute shorter and more scenic route than the inland Brand Highway which mainly services heavy traffic. The road also improved access to Wedge Island.
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.

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.
