Major roads across Sydney are being upgraded to improve traffic flow, reduce congestion, make our roads safer and meet the needs of the city’s growing population.  These upgrades include:


Once complete, the Western Harbour Tunnel will stretch 6.5km and connect the Warringah Freeway at North Sydney with the Rozelle Interchange, the M4 and the M5 via a tunnel beneath Sydney Harbour. It will be a much needed third Sydney Harbour crossing and offer a western bypass of the Sydney CBD.

The Warringah Freeway Upgrade would involve renovation of 4km of the freeway to provide connections for the Western Harbour Tunnel and Beaches Link and significantly the improve the efficiency one of Australia’s busiest and most complex road corridors.

Sydney Gateway will greatly improve the way we travel to Sydney Airport and Port Botany. It will deliver major new toll-free connections from the Sydney motorway network to the International and Domestic terminals.

Sydney Gateway will strengthen Sydney’s position as a global city, by expanding and improving the existing road and freight rail networks. Importantly, Sydney Gateway will provide a new route for around 10,000 trucks a day. This will divert trucks from local streets in Mascot by providing an alternative route, reduce travel times and congestion, and return local streets to the community.
