The next major stage of the Centenary Bridge Upgrade is on the horizon, with reconstruction works on the southbound side of the Centenary Bridge expected to commence in 2026.
Following the recent opening of the new northbound bridge to traffic, attention will soon turn to the original bridge structure, which will be rebuilt to form a modern, three-lane southbound crossing over the Brisbane River at Jindalee.
Once reconstruction begins, the existing bridge will undergo extensive works to upgrade its structure, road surface and safety features. When complete, the southbound bridge will match the new northbound crossing, delivering six traffic lanes across the river and significantly improving capacity along the Centenary Motorway corridor.
The southbound upgrade is expected to bring long-term benefits for the local community, including smoother traffic flow during peak periods, improved travel time reliability and a safer driving environment. Longer merge lanes and modern design standards are intended to reduce congestion and ease pressure on surrounding local roads.
Active transport users can also expect improvements. The broader Centenary Bridge Upgrade includes enhanced pedestrian and cycling connections, linking more seamlessly with existing shared paths and improving accessibility for residents travelling between Jindalee, Sinnamon Park and surrounding suburbs.
Importantly, the project has been staged to keep traffic moving throughout construction. With northbound traffic now using the new bridge, reconstruction of the southbound structure can proceed while maintaining lanes in both directions, minimising disruption for road users.
The Centenary Bridge Upgrade forms part of a wider investment in the Centenary Motorway, a key transport spine for Brisbane’s western suburbs. With traffic volumes continuing to grow, the southbound reconstruction represents a critical step in future-proofing the corridor for decades to come.
