Mounts Bay Road runs between William Street[2] and Winthrop Avenue in Crawley, continuing towards Fremantle as Stirling Highway and linking Perth with the University of Western Australia (UWA) and the riverside suburbs of Nedlands and Claremont.

To the east it travels to William Street and The Esplanade, along northern side of the Perth Convention Centre and the Elizabeth Quay Bus Station.

[1] Mounts Bay Road is also home to the Old Swan Brewery, as well as a number of expensive high rise apartments and hotels overlooking the river.

The signals are activated when queue detectors on the Kwinana Freeway on-ramp and Mounts Bay Road southbound, out of Perth, indicate there is sufficient traffic congestion.

[6][7] During the 2010s, The City of Perth planned to upgrade Mounts Bay Road to accommodate increasing traffic demand and improve accessibility.
