Caboolture-Bribie Island Road Upgrade

These upgrades will improve safety, ease congestion and improve traffic flow in critical areas on Caboolture–Bribie Island Road.

The Department of Transport and Main Roads' 20-year vision is to upgrade the road to provide a 4-lane, median-divided cross section for the length of the corridor. This includes a new, 4-lane Bribie Island bridge.

To deliver this vision, the department has developed the Bribie Island Road Upgrade Strategy, which sets out a 20-year masterplan for sequential upgrades to the road. The strategy identifies short, medium and long-term priorities to improve the safety, connectivity, reliability, capacity, transport efficiency and flood immunity of Caboolture-Bribie Island Road and will guide future investment decisions.

The Caboolture-Bribie Island Road and Old Toorbul Point Road intersection upgrade is the first upgrade to be delivered as part of the upgrade project.

The Old Toorbul Point Road intersection upgrade package includes traffic signal installation, constructing additional lanes on the Caboolture-Bribie Island Road approaches (2 lanes for each intersection approach in addition to left and right turn lanes), a signalised pedestrian crossing on Caboolture-Bribie Island Road.

After this upgrade is completed, the next identified priority for Caboolture-Bribie Island Road is the section between Old Toorbul Point Road and Saint Road. This upgrade will include duplication of the existing traffic lanes to a 4-lane, dual carriageway and intersection upgrades in line with the 20-year strategy for the corridor.
