Criticism of the quality and capacity of the highway has also been an issue. Reid Highway in Westminster (between Wanneroo Road and Mirrabooka Avenue) has no street lighting and has attracted both antisocial behaviour and a number of accidents. The stretch between Beechboro Road and West Swan Road has been similarly criticised, and the area east of the Mitchell Freeway was prone to heavy congestion due to its limited capacity as a two-lane single carriageway, before being upgraded to dual carriageway.
