Bribie Island Bridge Corridor Study

We have undertaken a study to identify a corridor for a future duplication/replacement of Bribie Island Bridge. The preferred corridor lies to the north of the existing bridge.

Bribie Island Bridge was originally constructed in 1963 and consists of 2 traffic lanes and a pedestrian pathway. The bridge is the only road link between Bribie Island and the mainland.

Continued growth in pedestrian, cyclist and freight traffic is placing increasing demand on the bridge, which is expected to reach capacity by 2031.

We have undertaken a study to identify a corridor for a new Bribie Island Bridge. The study looked at corridor options to the north and south of the existing bridge and considered factors such as:

  • potential impacts on property and services
  • geotechnical and environmental constraints
  • cohesion with existing infrastructure.

The preferred corridor for the new bridge is on the northern side of the existing bridge. This corridor option has impacts on fewer properties than a corridor to the south of the existing bridge and minimises impacts the environment by utilising existing cleared or modified areas where possible.

Benefits

  • Increases capacity
  • Improves network efficiency
  • Increases traffic flow
  • Reduces peak hour congestion
  • Better road access
  • Better active transport
  • Reduces maintenance

Key features

  • identifying potential impacts on property and services
  • identifying geotechnical and environmental constraints
  • cohesion with existing infrastructure.
