Sydney Gateway

Sydney Airport and Port Botany are critical international gateways helping to move people and goods around New South Wales. They are set to grow significantly over the next 20 years.

Sydney Gateway

Supporting this growth requires efficient connections to the city and Sydney’s other major centres and freight terminals. Part of the solution is Sydney Gateway.

Sydney Gateway will provide a new alternative route to enhance connections and reduce travel times to Sydney’s ports. It will provide improved access to all airport terminals and cater for increased rail freight, which will help take pressure off local roads.

Preliminary design consultation now closed

Thank you to the residents, businesses and community members who took the time to provide us with feedback on the Sydney Gateway preliminary design.

All comments received have been summarised in a Consultation Summary Report PDF, 2MB) which forms part of the scoping report submitted to the NSW Department of Planning & Environment. This is a key stage in the NSW planning process - read the scoping report (PDF, 7.8Mb).

We welcome ongoing feedback throughout the planning, design and delivery process.

What is Sydney Gateway?

Sydney Gateway will increase capacity and improve connections to the ports to assist with growth in passenger, freight and commuter movements across the region. It will strengthen Sydney’s position as a global city, expanding and improving the existing road and freight rail networks.

Sydney Gateway includes two key components:

road icon Road: A new alternative route to the domestic and international airport terminals from the Sydney motorway network at St Peters Interchange. Sydney Gateway includes a new dedicated flyover from Qantas Drive to the front door of the domestic airport. This route will bypass all traffic lights along major Sydney motorway networks to the domestic terminals. This project will be delivered by Roads and Maritime Services.

rail iconRail: Duplicate a three-kilometre section of the Port Botany freight rail line to increase capacity and improve service reliability. This project will be delivered by Australian Rail Track Corporation (ARTC).

Sydney Gateway is subject to Federal and State planning approvals.


Sydney Gateway will help make journeys easier, faster and safer:



  • Enable easier journeys to and from Sydney Airport and improved connections between the terminals
  • Provide new roads to Sydney Airport to help reduce congestion and cater for forecast growth in passenger and air freight
  • Provide access to the airport terminals for over-height vehicles (up to 4.6m), increasing the clearance from 4.3m
  • Improve the movement and support the growth of rail freight between Port Botany, freight terminals and logistic centres in Metropolitan and Western Sydney.



  • Will reduce travel times through improved road connections to the international and domestic terminals
  • Help reduce congestion in Mascot and Botany
  • Enable faster rail trips from freight terminals to Port Botany through the network
  • Improve the efficiency and increase capacity of the freight rail network to meet future demand
  • Reduce travel times when used with other Sydney motorway connections:
    • Save up to 40 minutes during morning peak times travelling between Parramatta and the Domestic Airport
    • Save up to 41 minutes during morning peak times travelling between Dee Why and the Domestic Airport
    • Save up to 22 minutes during morning peak times travelling between Campbelltown and the Domestic Airport



  • Will take trucks off local roads in Botany and Mascot by shifting more freight from road to rail – a freight train travelling to and from Port Botany is equivalent to up to 50 trucks
  • Take cars off local roads by providing new roads to the airport from the Sydney motorway network.
