Reid Highway / Malaga Drive Interchange


Latest News

Works are complete

Road users can now enjoy free flowing traffic conditions using the two new bridges on Reid Highway over Malaga Drive. The upgrade replaces the signalised intersection where road users regularly waited for several signal changes at peak periods.

The interchange works will improve safety and efficiency with four lanes for Reid Highway.

Motorists, residents and businesses are thanked for their patience and understanding during the construction phase of the works.


Project Overview / Scope

Malaga Drive is one of the major arterial links between the Morley precinct and the growing areas of Malaga, Ballajura and other north-eastern suburbs.

Since 1990, the Metropolitan Region Scheme has included a grade-separated diamond interchange at this location, with a six-lane freeway standard route on Reid Highway over a four-lane route on Malaga Drive. The original intersection was constructed in 1992 and since that time, traffic volumes and congestion have increased with the growth in residential and commercial development.

Nearly 75,000 vehicles pass through the intersection on a weekday, which results in vehicles waiting for several traffic signal changes at peak periods.

The interchange works have improved safety and efficiency at the intersection by constructing two new bridges to provide four lanes for Reid Highway traffic to flow uninterrupted over Malaga Drive.

We have designed a four-lane freeway standard route on the Reid Highway over a four-lane arterial standard route on Malaga Drive. Dedicated bus lanes are included as requested by the Public Transport Authority, and a Principal Shared Path (PSP) links the existing PSP. No land acquisition was required and all work was done in the existing road reserve.

 Project elements included:

  • Approximately 1.3 kilometres of four lane dual carriageway and 1.3 kilometres of single / two lanes off and on-ramps
  • Two new separate two lane bridges along Reid Highway over Malaga Drive with sealed shoulders to provide vehicle breakdown storage and safe on-road cycling across the bridges
  • Principal Shared Path (PSP) which will tie in to existing paths
  • Realigning pedestrian and cyclist facilities on the east side of Malaga Drive and provision for cycling facilities during construction
  • New pavement and road markings in the project area of Malaga Drive
  • Installing traffic signals at the new off and on-ramp connection to Malaga Drive
  • Widening Malaga Drive to provide bus lanes in each direction through both sets of traffic signals
  • Modifications to Reid Highway on-ramps to provide future ramp metering
  • Installing foundation intelligent transport systems consisting of optic fibre communication network, vehicle detection systems and closed circuit television
  • Street lighting, safety and noise barriers and screen walls; and
  • Landscaping, vegetation and public art

To provide enough long-term capacity on Reid Highway, and to save costs on future expansions, the bridges were built to eventually cater for three lanes in each direction. A double right-turn facility is included to cater for heavy westbound-northbound traffic movement.

The key benefits this project are expected to deliver are:

  • Improved traffic flow
  • Reduced congestion and delays
  • Reduced road user costs
  • Reduction in traffic crashes
  • Improved public transport; and
  • Reduced vehicle emissions


Community Engagement

The Reid Highway / Malaga Drive Construction Reference Group (CRG) consisted of residents, local ratepayers, environmental groups, businesses, and other interested parties. Members of the CRG represented the community and provided input and feedback into the design and construction stages of the project.  The CRG has completed its work for this project, and we sincerely thank all members for their input and involvement during the construction.


The CRG minutes are available in the Publications Section below.
