Reid Highway Duplication - Duffy Road to Erindale Road

 

Latest news

This project was designed to improve traffic flows and safety, with the following enhancements provided:

  • Additional lane capacity on Reid Highway between Duffy Road and Erindale Road
  • New traffic signals at Duffy Road South / Reid Highway intersection. A dedicated left turn into Reid Highway (westbound) and two right turn lanes heading east have also been constructed.
  • A new northbound loop-ramp at Mitchell Freeway.
  • Extending the right turning lanes at the intersection of Reid Highway and Erindale Road to improve traffic flow at the intersection.
  • Installing a traffic barrier to separate highway traffic from the shared path on the existing bridge over Mitchell Freeway.
  • Other works including road re-surfacing, modification to traffic islands, the construction of a retaining wall and shared path as well as the installation of noise and visual privacy screens.

The majority of works were completed in June 2016. Landscaping between Erindale Road and Marmion Avenue has been deferred until winter 2017. The intersection of Reid Highway and Mitchell Freeway contains exposed embankments which have a high concentration of limestone. Although limestone-tolerant plants are selected, these areas have a reduced landscaping requirement because of the difficulty of obtaining successful germination rates. It is expected that a number of plants will fail to thrive each year, so this germination/mortality rate is monitored to determine where infill planting will be required in subsequent winters.

New hydromulch and additional infill planting will be added here next winter, when conditions are most favourable, as well as in other areas throughout the project identified by the ongoing monitoring.

A key milestone for the project was the bridge beam lift at Mitchell Freeway and Reid Highway, which can be seen on our time-lapse video.

 

Project benefits

The key benefits this project have delivered are:

  • Improved intersection efficiency through a reduction in the level of congestion, delays, conflict points, crash frequency and lost travel time to all road users
  • Improvements to the shared path over the Reid Highway Bridge (this includes the provision of a barrier to separate the path from traffic)
  • Improved road safety with approximately 2.2 kilometres of undivided carriageway upgraded to divided dual carriageway
  • Improved access to Mitchell Freeway (north)
  • Improved road network performance resulting in improved access to areas of employment, industry and residential growth
  • Reduced congestion by creating an alternative, more direct route, which will also reduce transport costs and vehicle emissions
  • Improved amenity in adjoining suburbs by removing through traffic from residential streets; and
  • Greater capacity for future traffic increases

 

Community engagement

Community engagement on the Reid Highway Duplication - Duffy Road to Erindale Road section commenced in November 2013 with the distribution of the first Project Newsletter to surrounding communities.

Following distribution of the first newsletter, we received additional queries about the project and we have developed a set of Frequently Asked Questions to provide a greater understanding of the project. Additionally, a concept plan is also available.

We sincerely thank the Community Reference Group (and later Construction Reference Group) members who kindly donated their time to provide important input into the project.
