Reid Highway Dual Carriageway 

Altone Road to West Swan Road

  • Widening Reid Highway to dual carriageway and construction of the Arthur Street Bridge
  • Construction is due for completion by mid-2020
  • Improve safety and ease congestion


This is the last section between Marmion Avenue and Great Northern Highway that is not a dual carriageway. The dual carriageway between Beechboro Road North and Altone Road is now under construction as part of NorthLink WA.

Works include:

  • A four kilometre, two lane second carriageway between Altone Road and West Swan Road (construction to occur on the southern side of the existing carriageway)
  • New shared path and local links on the southern side of the highway
  • Modifications to Reid Highway and West Swan Road intersection
  • A new bridge over Reid Highway, connecting the northern and southern sections of Arthur Street
  • Install bridge beams and deck for a second carriageway across Bennett Brook
  • Extend the underpass to link Victoria Road
  • Noise walls (location and design yet to be determined)
  • Signage, fencing, drainage, landscaping and street lighting

Project Update

Construction Update - July 2019

The Reid Highway Dual Carriageway project is gathering speed, with detailed design approaching 85% and early works taking place across various areas of the site. This includes vegetation clearing and fencing in preparation for construction. For more information and lookahead to upcoming works, please see our latest July Construction Update

Clearing works during June and July

To prepare for construction, we will shortly commence a program of vegetation clearing in the project area. The majority of the clearing will take place directly to the south of the existing westbound carriageway, however, there will also be some activity on the northern and southern sections of Arthur Street. Read more in ourJune Construction Update.

Fact Sheet - Building the Arthur Street Bridge

Construction of the Arthur Street Bridge over Reid Highway will begin in July 2019. Our latestFact Sheet explains how the bridge will be constructed and the activities the community are likely to see in the months ahead. 

Stockpiling update

The stockpiles of crushed rockbase at the intersection of Reid Highway and Daviot Road have been sprayed with hydromulch to create a protective seal and mitigate the spread of dust.

This material will be used during the construction process for this project, and in particular for the new bridge connecting the southern side of Arthur Street in Caversham with the northern side of Arthur Street in Dayton.


This $70 million project is jointly funded by the Australian and State Governments as part of a $2.3 billion package of road and rail infrastructure works.
