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

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

Updates and announcements

We will be on site for the final stage of work between Monday 16th July and Friday 28th September 2018, weather permitting.

Temporary traffic changes will remain to ensure the work zone is safe.

The northbound cycle lane along Forest Way, between Mona Vale Road and just south of Garigal Road, is still temporarily closed.

Cyclists travelling along this section of Forest Way will need to join the main (left) northbound traffic lane through the construction zone.

All affected cycle lanes will open again at the end of the project.
