Connection to St Peters Interchange

Access into the International Terminal from Marsh Street, Arncliffe, remains the same.

Access to the Domestic Terminals from O’Riordan Street and Joyce Drive remains the same.

All other access will be via Sydney Gateway.

For drivers travelling from the M8 tunnels to Sydney Airport, the existing access via Gardeners Road and Euston Road will not be removed once Sydney Gateway connects to St Peters Interchange. Drivers can continue using these routes if they choose. However, Transport encourages drivers to research the route that suits them best as the new road connections may be an easier and faster route.   

Drivers in the local area surrounding Sydney Airport will continue to use Gardeners Road and other local roads to access the International and Domestic Terminals. There are no ramp connections from local streets onto Sydney Gateway roads at St Peters Interchange.   

Journeys to Port Botany for heavy vehicles already using Airport Drive, Qantas Drive and Joyce Drive won’t change when Sydney Gateway completes its final traffic change.   

The closure of the right turn into the Domestic Terminals from Qantas Drive removes a phase from the traffic lights and improves the function of the intersection.  

Heavy vehicles coming from Port Botany wanting to travel towards Parramatta and Blue Mountains will be able to access the M8 tunnels faster using the new Sydney Gateway roads, rather than local Mascot streets.   

In total there will be 13 heavy vehicle stopping bays across the Sydney Gateway project. These bays are important for the safety of all drivers and will minimise the risk of over height vehicles using the M8 tunnels.  

Heavy vehicle drivers can continue to access information on height, load and width restrictions on Transport’s website. The website includes information for trucks in NSW and a NSW oversize over mass load carrying vehicles network map.   

New wayfinding signs will be installed across the project and on the connecting motorways, and over 150 new road markings will help guide drivers to and from Sydney Airport.   

Signage is determined using strict guidelines and has been reviewed through an external qualitative testing process with drivers across Greater Sydney.   

Additionally, temporary digital signs will inform drivers about traffic changes at least two weeks prior to the final traffic switch taking place and will continue for one week immediately after, or longer, if required.    

To help drivers learn their journeys and to become familiar with new road signage, driver view videos will be available on the projects interactive portal showing the new routes between the M8 tunnels and Sydney Airport - nswroads.work/SydneyGatewayOpening.

Sydney Gateway will open in the coming months.  

Prior to project completion, there will be four key traffic changes. These changes have occurred progressively since November 2023.  

Once all electrical work (ITS) is complete, most of Sydney Gateway will be 70km-per-hour. Two sections will be less than 70km-per-hour including:  

• Deborah Lawrie Flyover which is 60km-per-hour on approach to the ramp and 40km-per-hour while on the bridge.   

• A south bound ramp between the Domestic and International Terminals will be 60km-per-hour for around 400 metres to ensure safe movement around the bend.   

Some sections of Sydney Gateway will temporarily remain 60km-per-hour until electrical work is complete on the variable speed zones. This work is expected to take a couple of months and will not impact the opening of the project.
