Airport Link, Northern Busway (Windsor to Kedron) and Airport Roundabout Upgrade project

Brisbane, Queensland, Australia

Client: Queensland Government

Parsons Brinckerhoff Role: (In joint venture): Tunneling, Road, Geotechnical, Electrical and Mechanical, Structural and Drainage Design

 Show Project Details

The Queensland Government appointed BrisConnections to deliver the $4.8 billion Airport Link, Northern Busway (Windsor to Kedron) and Airport Roundabout Upgrade project — Australia’s largest road infrastructure project. The project comprises two tunnels and a new airport connection — the 4.1-mile (6.7-kilometer) mainly underground Airport Link toll road, the Windsor to Kedron section of the Northern Busway, and an upgraded interchange providing improved access to the Brisbane Airport precinct.

Parsons Brinckerhoff and Arup in joint venture (PBAJV) were engaged to deliver the detailed design for this public private partnership (PPP) design-and-construct project. Design features include: --tunnel boring machine tunnels: twin-tube, two-lane uni-directional --large-span mined tunnels providing three-lane uni-directional vehicular travel, with underground intersections --high-capacity interchanges providing access to the tunnel infrastructure and existing road network --high-quality urban design and finish.

Airport Link toll road has provided a critical new link between Brisbane’s northern suburbs and two of south-east Queensland’s most important economic centers — the airport and the city. The Northern Busway (Windsor to Kedron) provides a dedicated busway tunnel and surface infrastructure for a high-capacity rapid transit system. The Airport Roundabout Upgrade is a vital piece of infrastructure required to improve access to the airport and surrounding economically important areas. The design solution for this project replaces the existing airport roundabout with grade-separation of the East–West and Gateway arterial roads, supported by a fast-diamond intersection.
