Sydney Gateway will be officially opened on Sunday 1 September 2024 as the new roadway project improves access to Sydney Airport.

The new five-kilometre roadway will save travellers 17 minutes between Sydney Airport and the St Peters Interchange, which connects to some of Sydney’s most important roads, including the M8 and the M5 and M4, to Western Sydney.
NSW Roads Minister John Graham thanked the 8,000 workers who worked on the project during its nearly four-year construction.
“I want to thank the 8000 workers who built Sydney Gateway, part of the most skilled and experienced infrastructure workforces we have in Australia or anywhere around the world.”
“Transport for NSW is working closely with Sydney Airport for the smoothest start, but I urge all Sydney drivers to take a moment to familiarise themselves with the animations, know their route and expect some initial traffic impacts as fellow drivers also get familiarised.”
Seymour Whyte is proud to celebrate the official opening of the Sydney Gateway Project today [Friday 30 August], in partnership with John Holland and Transport for NSW.
With 19 new bridge structures, more than 5km of new roads and over 3km of new pedestrian and cycle paths, this monumental infrastructure project connects Sydney’s road network to the airport and Port Botany, streamlining access and boosting the city’s connectivity. Live traffic will begin flowing this Sunday 1 September 2024.
Project Director Andrew Deck was extremely proud of our team’s achievements.
“A huge congratulations to everyone who played a part in bringing this visionary project to life. Together, we’ve set a new standard for collaboration and excellence in our industry, creating a legacy that will benefit Sydney for generations to come.”
Sydney Gateway will provide an alternative option for an estimated 10,000 trucks per day. Trucks driving from Sydney Airport to Port Botany will be able to use this option, reducing the number of trucks on local streets.
Final commissioning has been occurring this week through Transport for NSW. The organisation will also set up a joint operations centre at the Transport Management Centre. It will monitor and react to congestion and traffic incidents as the new Sydney Gateway integrates with the road network.
Seymour Whyte began the work in 2021 in a joint venture with John Holland and partners Arcadis and AECOM delivering design work as a joint venture.

Josh Murray, Transport for NSW secretary, said motorists should prepare for the Sydney Gateway’s opening this weekend.
“There are always impacts when opening large infrastructure projects as drivers get used to new conditions,” he said.
“We have been working hard to ensure we are well prepared to welcome motorists onto the newest section of Sydney Gateway, with the Joint Operations Centre at the Transport Management Centre crucial to this.
“We want people to reap the benefits of the new road connections straight away, so we are eager for as many people as possible to watch the in-car driver animations as these provide a perfect opportunity to see what is coming before opening.
“The animations include the signage and road markings that drivers will see in the M8 tunnels and on the new adjoining surface roads, helping them to navigate the new routes to and from the Sydney Airport precinct.”
