About

Seymour Whyte — in a joint venture with John Holland — will deliver the toll-free Sydney Gateway motorway, a design and construct road project that links the airport precinct, Port Botany and the surrounding road network to the newly opened St Peters Interchange.

The project has been divided into two separate works packages to address the nature of works, the many stakeholder interfaces and the innate risks.

Stage 1: International Terminal and Qantas Drive Connection

  • St Peters Interchange Connection: a new elevated section of road extending from St Peters interchange to the Botany Rail Line, including an overpass over Canal Road
  • Terminal 1 Connection: a new section of road connecting Terminal One with St Peters interchange connection, including a bridge over Alexandra Canal and an overpass over the Botany Rail Line
  • Qantas Drive Upgrade and Extension: widening and upgrading Qantas Drive to connect Terminals 2 & 3 with the St Peters Interchange connection, including a high-level bridge over Alexandra Canal
  • Terminal Links: two new sections of road connecting all three Terminals, including a bridge over Alexandra Canal
  • Terminals 2 & 3 Access: a new elevated viaduct and overpass connecting Terminals Two and Three with the upgraded Qantas Drive.

Stage 3: Domestic Terminals Access

  • A new section of road and an overpass connecting Sydney Airport’s northern lands on either side of the Botany Rail Line (the northern lands access)
  • A new section of road, including a signalised intersection with the Terminal 1 connection and a bridge, connecting Sydney Airport’s existing and proposed freight facilities on either side of Alexandra Canal (the freight terminal access).

We are delighted to continue our working relationship with John Holland and the NSW Government; and to be awarded the Sydney Gateway contract to improve connectivity for motorists and active transport users. This critical motorway link will make Sydney more connected than ever before. We are proud to be part of this project that will be the gateway to the city for residents and visitors.

This award demonstrates the civil engineering and technical ingenuity within our joint venture partnership. Together, we draw on our combined proven capability to efficiently deliver major infrastructure projects for an integrated road and public transport network. We are committed to working closely with our local suppliers, local communities and the government to deliver this important project safely and efficiently”
