Within two years of its formation in 1926, Western Australia's new Main Roads Board became responsible for the state's arterial and trunk roads, which were declared 'main roads' under the Main Roads Act.
The main road to Geraldton branched off the Perth–Meekatharra road at Walebing, near Moora, travelled an inland route via Mingenew to Dongara, and then continued north along the coast to Geraldton.
A new main road from Perth to Geraldton via Mogumber was proposed in the 1940s, but was rejected by the Minister for Works, who considered the development of parallel routes infeasible given that traffic was light.

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.

From the 1950s, increasing development between Perth and Geraldton saw the planning and establishment of a road network linking Dongara and Gingin – though the roads were not initially intended to become a highway.
Early surveying of the roads, in the 1950s, was undertaken from within a light aircraft flying over the area.
This was one of the first times in Western Australia that this technique was used.
Wide road reserves, up to 200 metres (660 ft) in width, were acquired from crown land and pastoral leases.
This allowed native wildflowers to survive and flourish on public land, providing aesthetically pleasing and interesting views to reduce road hypnosis and driver fatigue.
The road would also be made safer by removing natural roadside obstacles, and replacing them with shrubs and more wildflowers.

Construction of new roads that would eventually be part of the Brand Highway began in 1959.
Various segments were completed as the need arose, until in 1975, there was a new link between Perth and Geraldton.
The route reduced the distance between the cities by 78 kilometres (48 mi), and had a total cost of $4.2 million.
On 14 February 1975, the new road was gazetted as part of the Geraldton Highway, with the old route via Moora renamed The Midlands Road.
It was officially opened on 4 April 1975 by the Minister for Transport, Ray O'Connor at Eneabba.

One year later, the road was named Brand Highway after Sir David Brand, who was Premier of Western Australia from 1959 to 1971 and also held the local electorate of Greenough from 1945 to 1975.
The change of name from Geraldton Highway to Brand Highway was gazetted on 12 March 1976.
Then-premier Charles Court officiated a ceremony held on 30 April 1976 at a tourist information bay in Dongara, where a plaque was unveiled commemorating the naming of the highway.

The northern end of Brand Highway was upgraded as part of Stage 1 of the Geraldton Southern Transport Corridor, the biggest individual project in the early 2000s across all of rural Western Australia.
The project, constructed between March 2004 and December 2005 at a cost of $92.5 million, involved the relocation of railway tracks, five kilometres (3.1 mi) worth of road works, and grade separation of roads.
Brand Highway's northern terminus at North West Coastal Highway was upgraded from a roundabout to an interchange.
An overpass was built for nearby Durlacher Street to cross North West Coastal Highway, which was made into a dual carriageway in the vicinity of the interchange.
Stage 2 of the project, constructed between December 2008 and December 2009, provided a new single carriageway connection to Geraldton–Mount Magnet Road, with access to Geraldton Airport.
