Drumpellier Drive is a north-south road linking Ellenbrook with Reid Highway in the north-eastern suburbs of Perth, Western Australia.

The southern section was opened as Lord Street, and was the main link between Ellenbrook and the rest of Perth until the extension of Tonkin Highway north to Gnangara Road.

Drumpellier Drive then passes Gnangara Road, where it heads past Ellenbrook, before terminating at a roundabout with The Promenade.

[3][4] The first section of what is now Drumpellier Drive was an unsealed road along the perimeter of Caversham Airfield, which was constructed during World War II.

[7] From the 1990s, there has been a road reserve designated for the proposed Perth Darwin National Highway which runs through and alongside Lord Street and Drumpellier Drive.

The Swan Valley Bypass was proposed to be built in that road reserve, partially superseding Lord Street and Drumpellier Drive.

[9] In July 2011, the state Liberal government's Public Transport in Perth in 2031 plan committed to a bus rapid transit (BRT) service along Lord Street between Ellenbrook and Bassendean station.

Estimated to cost $49 million, the new route was a 9-kilometre (5.6 mi) dedicated busway along Lord Street between the Ellenbrook town centre and Marshall Road.

[15][16][17] A request for tenders was released in July 2016[18] and in November 2016, CPB Contractors was selected as the preferred proponent, with the cost by then having risen to $55 million.

From 19 July 2022 to February 2024, Drumpellier Drive was diverted via Isoodon Street to allow for a pedestrian underpass to be constructed next to Whiteman Park station.

[28][29] The ultimate plan for the intersection of Reid Highway, Drumpellier Drive and Daviot Road is for a grade separated interchange to be built.
