Stage 3 - Mona Vale Road West upgrade - McCarrs Creek Road to Powder Works Road

Updates and announcements

Roads and Maritime Services is carrying out survey and geotechnical work along Mona Vale Road from McCarrs Creek Road to Powder Works Road until the end of August. View or download the notification (PDF, 365Kb).

Our working hours will be from 7am to 6pm, Monday to Friday, weather permitting.

There will also be up to 16 night shifts of geotechnical and survey work carried out until the end of August between 6pm to 7am, Monday to Friday, weather permitting.

Roads and Maritime is currently preparing a Review of Environmental Factors to examine potential impacts of the proposed upgrade to Mona Vale Road (between McCarrs Creek Road and Powder Works Road) and outline measures to reduce and manage the impacts.

This additional investigation work will be used in conjunction with the Review of Environmental Factors, which will be on display later this year.

We will continue to keep you informed at key stages of the project.

Project background

The NSW Government is planning to upgrade Mona Vale Road from two lanes to four lanes between Terrey Hills and Mona Vale. The project will be staged to provide customers with a better travelling experience and to improve safety and traffic efficiency. Mona Vale Road West currently experiences congestion in peak periods and requires upgrading to increase capacity and reduce travel times. The proposed road upgrade for Mona Vale Road West would provide:

  • Additional lanes for climbing and descending to improve travel time in both directions
  • Widened lanes and shoulders and median separation to improve safety
  • 80km/h speed limit between Mona Vale and Belrose once the road upgrades for both Mona Vale Road East and Mona Vale Road West are completed
  • Facilities for cyclists, pedestrians and recreational horse riders.

What is happening now?

Roads and Maritime Services developed a preliminary concept design for both Mona Vale Road East and West and sought feedback from the community and stakeholders on the proposed upgrades during October and November 2014. We would like to thank everyone who took the time to consider the proposals and provide feedback.

We received feedback from 94 people. The majority of the comments raised related to the natural environment, safety and suggested changes to both proposals:

  • Natural environment – The feedback focused on flora, environmental concerns including air and water quality, fauna safety, health of native animals and fauna habitat
  • Project – The feedback received generally provided support for the project, but there were also some objections to the project. There were also a number of suggested changes and additions to both of the proposed preliminary concept designs
  • Safety – The feedback also focused on the safety of all road users including motorists, drivers of heavy vehicles, pedestrians and cyclists and the implications of heavy vehicle movements on safety.

Roads and Maritime has considered all the feedback about the proposed Mona Vale Road East and West upgrades. We have prepared a community consultation report which provides a summary of the comments and our responses.

Next steps

Roads and Maritime is currently preparing the Review of Environmental Factors (REF) to examine the potential impacts of the proposed upgrade to Mona Vale Road West and outline measures to reduce and manage the impacts. The REF will be placed on display for community and stakeholder comment in the first half of 2016.

What road upgrades are being proposed?

Roads and Maritime has developed a preliminary concept design for Mona Vale Road West, which includes upgrading the 3.2 kilometres of Mona Vale Road between McCarrs Creek Road and Powder Works Road from a two lane undivided road to a four lane divided road. We plan to locate most of the widening on the northern side of the road.

The key features of the proposed upgrade would include:

  • Widening Mona Vale Road between McCarrs Creek Road and Powder Works Road from two lanes to four lanes with a central concrete safety barrier
  • Providing 2.5 metre-wide shoulders along the length of Mona Vale Road between McCarrs Creek Road and Powder Works Road to allow a safer area for breakdowns and on-road cyclists
  • Widening the intersection of Kimbriki Road and Mona Vale Road to replace the existing intersection with new traffic lights and signalised pedestrian crossings. High retaining walls on the southern side of Mona Vale Road will be needed to widen the intersection
  • Widening Mona Vale Road to the west of Kimbriki Road to provide a westbound truck climbing lane
  • Widening and upgrading the intersection of Mona Vale Road and Tumburra Street to improve safety. The upgrade will provide a new underpass connecting Tumburra Street with Mona Vale Road. Westbound through traffic on Mona Vale Road will travel over the intersection
  • Closing traffic access to Mona Vale Road from Addison Road. The existing intersection would only be used as an alternate exit from Addison Road in the event of a bush fire or other emergency. A new road joining Addison Road and Tumburra Street would be provided to allow access to Mona Vale Road
  • Providing a utility corridor for gas, electricity and network cables away from Mona Vale Road parallel to the local road network
  • Providing a multi-use path along the length of the project to connect Ingleside to Terrey Hills (for pedestrians, cyclists and recreational horse riders). The path would generally follow the alignment of the proposed new utility corridor Mona Vale Road West upgrade – McCarrs Creek Road to Powder Works Road
  • Changing the speed limit from 70 km/h to 80 km/h once the road upgrades for both Mona Vale Road East and Mona Vale Road West have been completed.
  • Investigating fauna crossings.
