Centenary Bridge, Motorway beam bridge in Brisbane, Australia

Centenary Bridge is a motorway crossing of the Brisbane River carrying the Centenary Motorway between Fig Tree Pocket and Jindalee. It has footpaths for pedestrians, and in 2023 it was used by 85,000 vehicles per day. A second adjacent bridge is under construction beside it.

The original two-lane bridge opened in 1964, financed by LJ Hooker, the developer of the Centenary suburbs of Jindalee, Mount Ommaney and Westlake. A duplication to two lanes each way was officially opened by Main Roads Minister Russell Hinze on 27 March 1987. Construction of a second adjacent bridge began on 20 April 2023.

The bridge takes its name from the Centenary Suburbs of Jindalee, Mount Ommaney and Westlake, which it was built to serve; developer LJ Hooker financed the original 1964 crossing. Its opening ceremony in 1987 was performed by Russell Hinze, then Minister for Main Roads. Today the structure carries about 85,000 vehicles a day as part of the Centenary Motorway.

The bridge carries substantial daily traffic and provides dedicated paths that make crossing by foot or bicycle straightforward. These separate ways ensure safety and comfort for non-vehicular users on both journeys.

During the 1974 floods, authorities sank a barge that had collided with the structure using explosives to prevent potential collapse from water blockage. This emergency measure protected the bridge from damage during the extreme flood event.
