Eyre Highway is a 1,664-kilometre (1,034 mi) highway linking Western Australia and South Australia via the Nullarbor Plain. Signed as National Highways 1 and A1, it forms part of Highway 1 and the Australian National Highway network linking Perth and Adelaide. It was named after explorer Edward John Eyre, who was the first European to cross the Nullarbor by land, in 1840–1841. Eyre Highway runs from Norseman in Western Australia, past Eucla, to the state border. Continuing to the South Australian town of Ceduna, it crosses the top of the Eyre Peninsula before reaching Port Augusta.
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.

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.

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.
In Western Australia, Highway 1 is a 5,305-kilometre (3,296 mi) long route around the state, from the South Australian border near Eucla to the Northern Territory border near Kununurra. Highway 1 continues around the rest of Australia, joining all mainland state capitals, and connecting major centres in Tasmania. All roads within the Highway 1 system are allocated a road route numbered 1, M1, A1, or B1, depending on the state route numbering system. In Western Australia, most of the highway is designated as National Route 1; however, the sections in the north-east and south-east of the state that are concurrent with the National Highway routes linking Perth to Adelaide and Darwin are designated as National Highway 1.
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 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.
