 Prior to the opening of this realignment however, the extension of Joondalup Drive from Wanneroo Road to Neaves Road was also completed and opened to traffic.This in turn caused a large number of heavy westbound vehicles to deviate through local roads within Banksia Grove to connect with Joondalup Drive.As a consequence of this, the City implemented an order to limit the types of vehicles allowed to pass through the suburb and imposed on-the-spot penalties of up to $5,000 for offenders.
