Update: Caboolture–Bribie Island Road works progressing toward 2026 completion

By Chase Christensen 

Motorists travelling along Caboolture-Bribie Island Road will continue to experience changed traffic conditions as major upgrades move forward between Old Toorbul Point Road and Volz Road. The Department of Transport and Main Roads (TMR) has confirmed that its contractor is actively working to minimise delays and keep the project on track for an early-to-mid 2026 completion. 

To ensure the safety of drivers and construction workers, a 40km/h speed limit is currently in place during weekday work hours. Outside of construction times, speed limits vary — westbound traffic is restricted to 60km/h, while eastbound limits range between 60km/h and 80km/h, depending on the section. TMR’s contractor will continue monitoring traffic flow and adjusting management strategies to reduce disruptions where possible. 

Lane closures are being scheduled outside of peak travel times, helping to maintain smoother movement through the busy corridor. A temporary traffic switch took place on August 18, 2025, weather permitting, shifting both eastbound and westbound vehicles onto the newly completed westbound carriageway for about three months. The change allows crews to continue work on the next stage of the project while maintaining access for local and through traffic. 

The Caboolture-Bribie Island Road project aims to deliver a safer and more efficient route for the growing number of motorists travelling between the Bruce Highway and Bribie Island. Once complete, the road will expand from two lanes to four between Old Toorbul Point Road and just east of Saint Road, significantly reducing congestion and improving safety. 

Key design improvements include a new centre median to separate traffic travelling in opposite directions and intersection upgrades at Saint Road, McGrath Road and Old Toorbul Point Road. The Old Toorbul Point Road intersection will also include a U-turn facility for westbound light vehicles, while the Volz Road and Browns Road intersection will be signalised with a U-turn option for eastbound motorists. 

Cyclist safety has also been prioritised, with wider road shoulders and marked bike lanes at key conflict points. A shared path is being constructed along the northern side of the road from Old Toorbul Point Road to Volz Road, improving access for both pedestrians and riders. 

TMR said the project remained on schedule despite recent wet weather and ongoing construction challenges.  

“We understand that roadworks can cause inconvenience, but every effort is being made to keep traffic moving safely and efficiently,” a spokesperson said. 

The Caboolture–Bribie Island Road upgrade forms part of a broader plan to enhance transport safety and reliability in the City of Moreton Bay. Once complete, the duplicated four-lane carriageway will better accommodate population growth, improve travel times and reduce the risk of head-on collisions. 

Regular project updates, including traffic changes and construction progress, are available on the Department of Transport and Main Roads website. Motorists are reminded to follow all signage and drive with care through work zones to protect the safety of road users and workers alike.
