Warringah Road upgrade

To increase network enhancements around the Northern Beaches Hospital,  the NSW government is upgrading Warringah Road. As part of the upgrade Transport for NSW will be:

  • building a 1.3 kilometre long underpass on Warringah Road
  • constructing three underpass bridges at the Forest Way, Hilmer Street and Wakehurst Parkway intersections
  • upgrading bus stops
  • upgrading new shared paths and pedestrian bridges
  • undertaking key intersection improvements.

This project is scheduled for completion in mid-2020.

Lane closures will be in place while Roads and Maritime Services to construct the Warringah Road underpass entry and exit.

From 8pm Monday 6 January to 5am Monday 20 January 2020, we will make the following changes on Warringah Road:

For westbound traffic we will:

  • close one westbound lane of Warringah Road from Allambie Road to Wakehurst Parkway.

 For eastbound traffic we will:

  • close one eastbound lane of Warringah Road from Altona Avenue to Allambie Road
  • maintain the right turn at Hilmer Street and Wakehurst Parkway.

Please refer to the project notification and FAQs for more information.

Thank you for your patience during this important work.

Traffic information

There will be minor traffic changes as construction of the 1.3 kilometre long underpass progresses.

Motorists at the Forest Way and Wakehurst Parkway intersections will notice a reduction in temporary traffic changes compared to those experienced throughout 2019.

Traffic delays and impacts to journey times will continue and we sincerely appreciate the support of residents and road users during this period.

To view more detailed information on current work locations and traffic changes, view the interactive map from the project home page.

We urge motorists to use alternative routes; avoid the area if possible during peak periods, allow extra travel time, and plan their journey ahead.

Icon of a busNew bus priority measures and facilities will provide:

  • increased bus services
  • improved public transport options
  • improved safety for pedestrians and cyclists

New facilities such as signalised pedestrian crossings at all intersections, shared paths and shared pedestrian bridges will also improve safety, public transport options and provide essential access through the area.

During construction, some bus stops need to be temporarily relocated or closed to allow essential work to occur. Pedestrian access is maintained at all times, although minor temporary detours may be in place. We will communicate these changes to users via notifications and signs posted at the bus stops.

The project team consults regularly with transport providers, local Council and other stakeholders on these bus and transport changes, which are also approved by Transport for NSW.
