Gateway Upgrade Project


The Gateway Upgrade Project involved upgrading of 16 kilometres of the motorway between Lytton Road and Miles Platting Road in the south, constructing an entirely new seven kilometre section of the motorway, north of the Brisbane River offering a more direct route to Brisbane Airport and the Port of Brisbane as well as duplicating the existing Sir Leo Hielscher Bridge (formerly the Gateway Bridge).


  • The $2.12 billion Gateway Upgrade Project is one of the largest bridge and road projects in Queensland’s history.

  • The project was a state government initiative, delivered by Queensland Motorways (now Transurban) with design, construction and maintenance undertaken by the Leighton Abigroup Joint Venture.

  • The project had the biggest Design, Construct and Maintain (DCM) contract in Australia’s history.
