Main roads with highway names
A `` main road '' is another type of road controlled by Main Roads Western Australia . [ 1 ]
Highways in Western Australia include both roads that are named as a highway, and roads that have been declared as a highway under the Main Roads Act 1930. The standard of highways range from two-lane roads, common in rural areas, to controlled access, grade separated freeways in Perth. In legislation, a highway is a type of road controlled and maintained by the state road authority, Main Roads Western Australia. Any road or section of road may be proclaimed a highway by the Governor of Western Australia, on the recommendation of the Commissioner of Main Roads, under Section 13 of the Main Roads Act 1930. Section 14 of the act allows for the creation of new highways. Main Roads assigns each highway a name and number, which may vary from the common road names used on road signs and by the general public. The highway number does not correspond to a road route that may be allocated to the highway, and some highways are not part of a numbered route.
