The NSW and Australian Governments have joined forces to deliver a long-awaited upgrade to Mona Vale Road West, unlocking a $500 million investment aimed at easing congestion on one of Sydney's busiest traffic corridors.

Mona Vale Road is a vital arterial route connecting Sydney's Northern Beaches to the city's northern suburbs. For years, drivers have faced daily bottlenecks along this narrow stretch of road, especially during peak commuting hours. The 3.4-kilometre section between McCarrs Creek Road, Terrey Hills, and Powder Works Road, Ingleside, has long been identified as a traffic choke point.

The Scope of the Upgrade

The project will expand this key section of Mona Vale Road from two lanes to four lanes, significantly improving traffic flow and safety. Key features of the upgrade include:

  • A new traffic signal intersection with Kimbriki Road, featuring dedicated turning lanes and a truck climbing lane.
  • Relocating the intersection with Tumburra Street by approximately 40 metres, allowing only left-turn access in and out.
  • Closing the Addison Road intersection to general traffic, restricting it to emergency vehicles only.
  • Constructing a new local road connecting Bungendore Street and Powder Works Road, using the existing Harvey Road corridor, and extending it east to the Mona Vale Road and Powder Works Road intersection.
  • Removing bus stops near Tumburra Street and re-routing bus services along the new local road and Tumburra Street to serve both current and future developments.

Benefits for Pedestrians, Cyclists and Wildlife

Beyond easing congestion, the upgrade incorporates features aimed at supporting sustainable transport and protecting local wildlife:

  • A shared-use pedestrian and cyclist path on the northern side of Mona Vale Road.
  • Upgraded street lighting and landscaping across the project area.
  • A 40-metre fauna bridge and two fauna underpasses to allow safe animal crossings.

Long-Term Investment for NSW

The NSW State Budget includes a $250 million commitment, matching the $250 million already pledged by the Australian Government. This investment reflects a joint priority to deliver essential infrastructure that supports the long-term prosperity of NSW without resorting to privatisation.

Government Statement

NSW Minister for Roads Jenny Aitchison stated: "The Minns Labor Government is committed to infrastructure that improves people’s lives in NSW."

This major upgrade is part of a broader focus on targeted infrastructure spending that aims to deliver immediate benefits to communities while preparing the state for continued population growth and development.

The project will not only reduce travel times but also improve road safety, public transport access, and environmental protections, offering a comprehensive solution to one of Sydney's most persistent traffic challenges.
