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

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

Parsons Brinckerhoff’s work on mass transit systems includes the planning, design, and maintenance of modern bus systems that greatly improve urban mobility, while meeting 21st-century priorities such as energy efficiency and lower emissions. Our services cover every major component of a bus rapid transit system, including bus lanes and busways, stations, and maintenance facilities. Parsons Brinckerhoff has worked on highly advanced bus rapid transit projects around the world—systems that combine the latest technology for efficient, low-impact vehicle operations with state-of-the-art busway, station, and signaling designs. Projects include U.S. systems such as the Franklin Corridor EmX system in Oregon (Eugene to Springfield), which is being expanded as part of a program to further enhance regional transit service, and the popular Metropolitan Area Express (MAX) and ACE Express bus systems in Las Vegas, Nevada. Our bus projects also include the South East Busway Extension in Brisbane, Australia—an expansion of an existing system that will help meet the transportation needs of growing local communities.

Bus rapid transit offers a distinctive combination of reliability and flexibility that makes it an effective solution to meet urban transit demands. PB’s broad technical and project management expertise—backed by more than a century of experience in the development of transportation systems worldwide—makes us an effective partner in the planning and development of advanced bus systems.
