Intersection improvements on Mona Vale Road and Forest Way, Terrey Hills

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

Updates and announcements

We are continuing with our work until Saturday 30 June 2018, weather permitting and excluding public holidays.

We have temporarily closed the cycle lanes along Forest Way during construction. The westbound cycle lane on Mona Vale Road near the intersection with Forest Way has also been temporarily closed. All affected cycle lanes will open again at the end of the project. Cyclists travelling along this section of Mona Vale Road and Forest Way will need to join the main (left) traffic lane through the construction zone.

Bus stop relocation

The bus stop south of Garigal Road on Forest Way will be permanently relocated to immediately north of Garigal Road as a kerbside bus stop. We expect the bus stop will be moved on Friday 9 February 2018.

Project background

The NSW Government is funding Mona Vale Road and Forest Way, Terrey Hills, intersection upgrades as part of its $300 million Urban Roads Pinch Point Program and its $225 million Pinch Point Program, which aims to reduce congestion and improve travel times on Sydney’s busiest corridors.

We will be on site until Saturday 30 June 2018, excluding public holidays, weather permitting. Our day work hours will be between 7am and 6pm from Monday to Friday and between 8am and 1pm on Saturday. Our night work hours will be between 8pm and 5am from Sunday to Friday.

Our work may be noisy at times but we will do everything we can to minimise its impact, including completing the noisier tasks by midnight.

Project objectives

The key benefits of the 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 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 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 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

Community engagement

Roads and Maritime sought community feedback on proposed improvements in May 2017. We have now prepared two Community Consultation Reports that summarise the feedback we received and our responses.

What happens next?

We will keep you updated as the proposal progresses.
