T junction with Guildford Road. History Collier Road has existed as far back as the early 1910s, being built along the border of several land grants by the Bayswater Road Board, the precursor to the City of Bayswater, as part of an agreement with the landowners. The road was built out of gravel. Later, the road was named Collier Road, after Philip Collier, the Premier of Western Australia from 1924 to 1930. In 1956, the Morley business district was zoned, centring on the corner of Collier Road and Walter Road. The late 1950s and early 1960s saw the land around Collier Road change from rural to suburban, as the suburbs of Morley and Embleton were developed. The 1960s saw the modernisation of Collier Road, with its steep hills flattened to gentle slopes. The decline of drive-in theatres had caused the Wirrina Drive-In, on the corner of Collier Road and Walter Road, to close in 1980. This provided an opportunity for realigning Collier Road to go along the eastern edge of the Morley business district, to allow the construction of one large shopping centre. At the time, Collier Road continued straight through the Morley business district, meeting up at an intersection with Walter Road and Wellington Road. Long standing businesses in the area, especially those along Collier Road, were strongly opposed to the idea, but the Bayswater council was for it. The realignment occurred in the middle of the 1980s, allowing the Galleria Shopping Centre to be constructed. Remnants of the old alignment remain, with a small portion of Collier Road, now named Old Collier Road used as an entrance to the Galleria Shopping Centre. Collier Road was being modified on its other end as well. On 16 December 1986, Collier Road was extended from Alice Street in Bassendean to Guildford Road. Between mid-2016 and early 2018, as part of the NorthLink WA construction project, Collier Road was realigned between Wright Street and Grey/Jackson Streets. A single-point urban interchange was built at the junction of Collier Road and Tonkin Highway, replacing the previous at-grade intersection. Also, traffic lights were added to Collier Road's junctions with Wright Street and Grey/Jackson Streets. The project's purpose was to make Tonkin Highway freeway standard and to replace the intersection of Collier Road and Tonkin Highway, which was the third most congested intersection in Western Australia in 2016.
