Centenary Bridge Upgrade

Building Queensland is partnering with the Department of Transport and Main Roads to develop a detailed business case for the Centenary Bridge Upgrade.

The Centenary Motorway plays a critical role within the broader South East Queensland transport network, providing a key link that connects the Western Corridor and inner and northern suburbs of Brisbane and the Australia Trade Coast Precinct. An analysis of major Brisbane River crossings revealed that Centenary Bridge has the highest lane utilisation and traffic congestion is expected to exacerbate over time.

The Centenary Motorway has progressively developed from a two-lane local arterial to an urban motorway; however, it has not kept up with the rapidly changing land use and demographic changes due to its operational and road design limitations. As a result, the strategic network is vulnerable to severe impacts on network performance and flow breakdown in the event of a traffic incident.

The detailed business case is investigating options to enhance the existing Centenary Bridge and active transport facility, and construction of a new bridge with an upgraded active transport facility.

The detailed business case is expected to be completed mid-2019.

Priority status: The Centenary Bridge Upgrade is part of the Centenary Motorway–Frederick Street to Sumners Road proposal identified in Building Queensland’s Infrastructure Pipeline Report. It is also reported as a priority initiative referred to as Centenary Motorway Capacity in Infrastructure Australia’s Infrastructure Priority List.
