Meet and talk with our team

It was our plan to hold our final community information session on Thursday 26 March at Fred Huntley Hall, North Sydney, which would have been the third session at this location. However, the health and safety of the community and our team is our priority and in light of the recent developments with COVID-19, we cannot proceed with our final face-to-face community information session.

Our team is available to facilitate a Facetime or online meeting at your convenience. If this is something you’re interested in, please email whtbl@transport.nsw.gov.au with your contact details, the best time to call you and a summary of the matters you wish to discuss, and we will contact you at your preferred time.

We apologise for any inconvenience if you were planning to join us and we thank you for your understanding. Please do not hesitate to get in touch with us should you need any further information.

Kind regards,
The project team

About the project

What is Western Harbour Tunnel and Warringah Freeway Upgrade?

The NSW Government’s vision for Sydney is one of an integrated road and public transport network that gives you the freedom to choose how and when you get around, no matter where you live and work.

One area of focus in Sydney is to complete the missing links in the motorway network to support the growth of our communities, places and economy, and enable people and goods to move safely and reliably around our city and beyond.

We know Sydney traffic can be frustrating, especially in peak hour. The Western Harbour Tunnel and Warringah Freeway Upgrade will change the way you travel across Sydney Harbour. This project will get you to places faster by improving capacity and providing new direct routes and reliability on both sides of the harbour.

This much needed new crossing of Sydney Harbour will be a game changer for our city. You will save time on your journeys and enjoy more direct bus routes between the Inner West, Sydney and North Sydney, with seamless connections to the future Sydney Metro and Sydney Trains.
We are now exhibiting the EIS and are seeking your important feedback to help us continue to shape this iconic project.

To make an official submission on the Western Harbour Tunnel and Warringah Freeway EIS please visit the DPIE website.

Why we need Western Harbour Tunnel and Warringah Freeway Upgrade

Population in our great city is expected to grow from five million to eight million in the next 40 years.

We also expect to see Sydney’s economic output double by 2031. This includes significant growth in high-skilled jobs in the Global Economic Corridor, which stretches from Macquarie Park and Chatswood to North Sydney, the Sydney CBD and beyond to Sydney Kingsford Smith Airport.

The Sydney Harbour Bridge, Warringah Freeway and Eastern Distributor have been identified as among Australia’s 30 most congested roads.

Improvements to existing transport networks and the creation of new transport connections will be essential for our city to continue to have a competitive economy and meet the growing needs of our communities.
