Traffic and commuters

Roads and Maritime has made temporary traffic changes so we can progress the upgrade of Warringah Road at Frenchs Forest. Warringah Road is one of Sydney’s busiest arterial roads. About 140,000 vehicles travel through the area every day. With population growth and increased employment expected across the Northern Beaches, the road upgrade will provide essential infrastructure to move motorists through the
Frenchs Forest area more efficiently.

When the project is complete road users will enjoy improved travel times and network reliability on Warringah Road and the surrounding road network.

We will continue to keep the community informed and monitor traffic alongside the Transport Management Centre to ensure we provide a safe environment for residents, commuters, pedestrians and cyclists travelling through the project area as well as for those working on the project.

Please view the animated video to see how it will look once complete.

Key traffic changes

Construction reaches peak activity between May and July 2018 and there are lots of changes ahead. The next stage of the project will see major traffic changes in Frenchs Forest from Saturday 26 May as we move into more extensive work on the Warringah Road upgrade.

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

Current work locations and traffic changes

Frenchs Forest Road

  • Frenchs Forest will reopen to two way traffic, widened to two lanes in each direction in late July 2018 providing key access and additional capacity to the hospital. We thank residents and patients for their patience and understanding during this important work.

The 1.3km Warringah Road upgrade will improve the performance of the road network and reduce congestion around the road network. Through traffic will flow along Warringah Road, bypassing three intersections. Completion of the underpass will improve travel speeds and reliability of travel on Warringah Road and the surrounding road network.

We are extremely grateful to residents and commuters for their ongoing patience while we deliver this important project for the Northern Beaches.

For more detailed information you can view or download the Traffic and Access Management Plan (TAMP) which describes how traffic is managed during construction, including how we ensure appropriate controls and procedures are in place to address potential traffic impacts.

Detour information

Alternative routes like Mona Vale Road or Pittwater Road may be better options for some journeys. You can also consider a real-time road app to help you find your best route based on live traffic data.

Are you a pedestrian or commuter in the area?

New 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.
