The NSW Government is funding two intersection upgrade proposals on Mona Vale Road and Forest Way as part of its Pinch Points Programs.

Updates and announcements

Roads and Maritime Services invites your feedback by Friday, 26 May 2017 on two proposals to improve the intersections of Mona Vale Road and Forest Way, and Forest Way and Garigal Road, Terrey Hills.

We propose to improve traffic flow and safety at these intersections by widening sections of the road, adding turning lanes, and providing new footpaths and a cycle bypass lane. For more information, please view or download the May 2017 – Project Update (PDF, 1.57Mb)

Project background

The NSW Government is funding two proposals as part of its $300 million Urban Roads Pinch Point Program and its $225 million Pinch Points Program, which aims to reduce congestion and improve travel times on Sydney’s busiest corridors.

Project objectives

The key benefits of the proposed intersection improvements on Mona Vale Road and Forest Way, Terrey Hills include:

  • Less congestion and improved safety on Mona Vale Road, with the extended dual right turn lanes providing room for about 16 additional cars, and reducing the incidence of rear-end and lane change crashes
  • Increased safety for bicycle riders, with a dedicated cyclist left turn lane from Mona Vale Road onto Forest Way
  • Improved access to the left turn lane from Forest Way onto Mona Vale Road, allowing left turning vehicles to bypass queued traffic on Forest Way
  • Reduction in queue lengths for motorists travelling westbound on Mona Vale Road

The key benefits of the proposed intersection improvements on Forest Way and Garigal Road, Terrey Hills include:

  • Less congestion and improved safety on Forest Way, with the additional northbound lane reducing queue lengths in peak periods, and reducing the incidence of rear-end and lane change crashes
  • Improved access to Garigal Road and to the Auslink Business Park with the new left slip lane from Forest Way
  • Improved overall intersection efficiency.

Key features

The proposed work at the intersection of Mona Vale Road and Forest Way, Terrey Hills includes:

  • Widening into the existing median on the western side of Mona Vale Road to accommodate an extended right turn bay onto Forest Way
  • Widening into the existing median on the eastern side of Mona Vale Road to accommodate an additional westbound through lane on Mona Vale Road
  • Modifying the existing westbound slip lane on Mona Vale Road from Forest Way to accommodate three through lanes on Mona Vale Road
  • Installing a ‘turn left at any time with care’ sign at the westbound slip lane from Mona Vale Road onto Forest Way and at the northbound slip lane from Forest Way onto Mona Vale Road
  • Widening into the existing median on Forest way between Mona Vale Road and Garigal Road to accommodate a dedicated left turn lane northbound onto Mona Vale Road
  • Modifying the left slip lane from Mona Vale Road westbound onto Forest Way, to accommodate the construction of a traffic island and dedicated cycle lane.

The proposed work at the intersection of Forest Way and Garigal Road, Terrey Hills includes:

  • Construction of a traffic island on the south-western side of the intersection to accommodate a northbound left slip lane from Forest Way into Garigal Road
  • Installing a zebra crossing from the newly constructed traffic island to the southern side of Garigal Road
  • Widening into the existing median on Forest Way to accommodate an additional northbound lane, through the Garigal Road intersection
  • Installing a ‘turn left at any time with care’ sign on Forest Way at the new slip lane onto Garigal Road
  • Relocating the existing northbound bus stop on Forest Way to the northern side of the Garigal Road intersection
  • Providing a new footpath to the relocated bus stop.

Community engagement

We encourage you to send us your comments on our proposal to:

Next steps

We will consider all feedback before deciding whether to proceed with the proposals.

The two projects would be constructed separately in order to minimise traffic impacts during construction.

Two separate community consultation reports will be prepared summarising the matters raised during the consultation period, and will be made available on our website.
