Centenary Bridge Upgrade

Project Details

  • Rating Type: V 1.2 Design and As Built
  • Location: QLD
  • Stakeholders: QLD Department of Transport and Main Roads,AECOM

The Centenary Bridge Upgrade in Jindalee proposes a new 3-lane northbound bridge, rehabilitation of the existing bridges to 3 lanes southbound, plus opportunities for improved active transport.

This extra capacity would provide greater efficiency and travel-time reliability between Brisbane's CBD and the western suburbs, between local destinations, and along the entire Centenary Motorway.

The planning study for the Centenary Motorway Upgrade identified possible staged upgrades along the Centenary Motorway from Sumners Road, Darra, to Frederick Street, Toowong. These staged upgrades are aimed at meeting the region's future transport needs and include options focused on safety, improving travel-time reliability, and new active transport opportunities for pedestrians and people who ride bikes. The Centenary Bridge carries more than 85,000 vehicles a day and current traffic modelling shows that by 2036, around 152,000 vehicles per day will want to cross the bridge.

Key features

- A new 3-lane northbound bridge.

- Remediation of the existing bridges to create 3 southbound lanes.

- Upgraded active transport facilities for pedestrians and people who ride bikes, with improved connections to the Western Freeway Bikeway and local destinations, including retention of the Jindalee Skate Park.

- Greater efficiency and travel-time reliability.


Hiighlight 1

The project demonstrated a net improvement to operational water quality from stormwater runoff that flows into the Brisbane River, which flows into the Brisbane River and Jindalee Creek. This was enabled by retrofitting stormwater treatment for existing pavements and the inclusion of a permanent water quality treatment train comprising of swales, vegetated buffer strips, bioretention basins, and gross pollutant traps for litter and sediment removal.

Highlight 2

A 15 percent reduction in material lifecycle impacts was achieved. Initiatives included retention of the existing bridge substructure and foundations while modifying the deck beams and slab, galvanising large beam sections to reduce re-applications of paint coatings over the operational phase, reductions in pile and column volumes due to design reconfigurations, and resurfacing of existing pavements.
