It is located within the northern suburbs of Perth, from Madeley in the west, to Henley Brook in the east.

Gnangara Road was upgraded to a four lane dual carriage way between Drumpellier Drive and Pinaster Parade, near Ellenbrook.

The works began in May 2012, and included traffic lights at the intersection of Gnangara Road and Drumpellier Drive, drainage, and kerbing.

[6] The state government committed $6.6 million to construct a second carriageway between Beechboro Road North and Drumpellier Drive, and an additional $14 million to complete the remaining 7.9 kilometres (4.9 mi) up to Alexander Drive which took place between 2013 and 2015.

[9] In 2019, the intersection was subsequently removed as part of the NorthLink WA project due both to the new parclo interchange with Tonkin Highway opening just to the east along with the carriageway itself crossing the path of Beechboro Road North (that road was made a cul-de-sac at its northern end accessible from near Hepburn Avenue).
