Major infrastructure upgrades are progressing in Caboolture, focusing on the Bruce Highway and Caboolture-Bribie Island Road, with several projects in planning, design, or construction phases.
Infrastructure Expansion Across the Caboolture Region
The Caboolture area is undergoing multiple large-scale transport upgrades, with business cases, design plans, and construction efforts underway across key corridors. These projects aim to address capacity, safety, and network efficiency demands brought by sustained regional growth.
Background on Highway Upgrades
Planning is in progress to upgrade the Bruce Highway between Uhlmann Road, Burpengary and Caboolture-Bribie Island Road. This section forms part of a larger corridor improvement plan stretching from Anzac Avenue to Caboolture-Bribie Island Road. The business cases for the two consecutive sections are being developed under a single planning study to support long-term solutions for traffic congestion and flood resilience.
Collector-Distributor Roads Chosen for Bruce Highway Corridor
Planning assessments found that adding general highway lanes would offer limited benefits due to weaving and merging caused by multiple interchanges and access points. As a result, collector-distributor roads have been proposed as the preferred solution. These roads will run parallel to the highway, diverting short-distance traffic and easing congestion.
Planned features include upgrades to the Caboolture-Bribie Island Road interchange, braided ramps to manage entry-exit weaving, and the construction of three new bridges over the Caboolture River. Lower King Street will also be upgraded, including signalisation at Mewett Street and expansion to four lanes.
These combined projects have received a total of $22 million in planning investment through joint federal and state funding, with construction timelines to be confirmed.
Dual Carriageway Expansions on Caboolture-Bribie Island Road
Design is underway to duplicate the section of Caboolture-Bribie Island Road from Hickey Road to west of King Johns Creek. This includes traffic signals at the Hickey Road intersection, a centre median, a shared path, and cycling infrastructure improvements. The project has a total investment of $59 million.
Separately, construction is ongoing between Old Toorbul Point Road and Saint Road. This stage involves upgrading to a 4-lane carriageway, intersection signalisation at Volz Road/Browns Road, and improvements to bike lanes and shared pathways. This project is funded at $48.23 million and complements a previously completed intersection upgrade in the same corridor.
Bribie Island Bridge Business Case Finalised
A business case has been completed for a new bridge between Sandstone Point and Bribie Island. The concept design outlines a two-lane eastbound structure with an active transport path. The existing 1963 bridge will be retained for westbound traffic. Additional works include road widening between Bestmann Road East and Benabrow Avenue, realignment of the Sylvan Beach Esplanade intersection, and traffic signals near Sandstone Point Hotel.
The $5.2 million planning stage was fully state-funded. Future timelines for design and construction remain under consideration.
Local Station Access and Western Bypass Planning
A transport study is in progress to enhance access to Caboolture, Morayfield, Burpengary, Narangba, and Dakabin train stations. The study aims to support active and multi-modal travel for the region’s growing population.
In addition, planning for Stage 4 of the Bruce Highway Western Alternative continues. The proposed 12.6-kilometre alignment between Moodlu and Beerburrum aims to reduce congestion on existing roads while avoiding rural residential zones. Feedback from public consultation closed in June 2025 and will inform final route protection.
Next Steps for Caboolture Transport Projects
Planning continues across all Caboolture-related infrastructure initiatives. Feedback on preferred options is currently under review, and design outcomes will guide future funding and construction timeframes. These works aim to support long-term growth and improve road and transport resilience across the region.
