Western Australia's Nomenclature Advisory Committee proposed in October 1940 that a highway name, Great Northern Highway, be used to describe the main route from Midland to Geraldton, and extending to areas further north. By July 1941, the committee's proposal had expanded to three highway names for the roads in the state's northern areas: Great Northern Highway for the Midland Junction to Wyndham road, North West Coastal Highway for the road linking Geraldton to Port Hedland and De Grey, and Geraldton Highway for the Walebing–Mingenew–Geraldton route. This road was gazetted as Geraldton Highway on 17 September 1943, superseding the previously used names of Choral Street, Yarma Street, Railway Road, Midland Street, Railway Street and Irwin Road.
