Queensland has unveiled a preferred design for a new four-lane bridge to Bribie Island, doubling traffic capacity while retaining the existing crossing for pedestrians and cyclists. Announced on Sunday (18 October), the project is in detailed design, with state funding committed and environmental and statutory approvals being progressed.
The Department of Transport and Main Roads' project description places the new bridge immediately north of the existing structure, with two traffic lanes in each direction. The old bridge would become a dedicated active transport connection, including access for people using mobility devices.
The existing bridge opened in 1963 and is the island's only road connection to the mainland. The department says the upgrade is intended to improve reliability, resilience and emergency access for a crossing used by residents, businesses, emergency services and visitors.
The works extend beyond the bridges. Caboolture–Bribie Island Road would be widened to four lanes between Bestmann Road East and Benabrow Avenue, while the Sylvan Beach Esplanade intersection would be realigned for safer turns. Traffic signals are also planned at the Sandstone Point Hotel access, alongside improved walking and cycling path connections on both sides.
Ground Investigations and Community Feedback
In its design announcement, the government said geotechnical investigations would begin during the week of Monday (19 October). Those investigations will gather information about ground and seabed conditions to inform design work and environmental assessments.
The department also lists hydrological and marine surveys in Pumicestone Passage among the investigations informing the design. It says engineering analysis, environmental data and community feedback will continue to shape the bridge, approach roads, intersections and active transport connections as detailed design progresses.
Residents can comment on key design elements, including what they want incorporated into the future walking and cycling bridge. The project's consultation hub also invites feedback on proposed marine park zoning changes and a works area. Consultation closes on Friday (27 November 2026).
As Brisbane Times reported, Transport and Main Roads Minister Brent Mickelberg expected the bridge to be finished before the 2032 Games. He put the expected environmental approval timeframe at two to three years, followed by an estimated three to four years of construction once approvals and detailed design were complete.
That pre-Games timing is the minister's expectation, rather than a fixed opening date. The department describes the scheme as a planned investment fully funded by the Queensland Government, with investigations and community input continuing to inform its delivery.
