Gympie Arterial Road and Strathpine Road Interchange upgrade

We have finalised the design to address safety concerns at the Gympie Arterial Road and Strathpine Road interchange at Bald Hills.

The design will transform this interchange into a diverging diamond interchange, an innovative intersection design that will reduce congestion, improve travel times and address safety concerns.

The new interchange, while unfamiliar to Australian drivers, will be easy to navigate and we will engage with road users to help drivers understand how to navigate the intersection.

We will keep the local community informed as the project progresses.

Benefits

  • Improves safety
  • Increases capacity
  • Reduces travel time
  • Reduces peak hour congestion
  • Contributes to economy
  • Contributes to regional growth

Key features

  • Right-turning traffic does not have to give way to opposing traffic making the intersection both safer and more efficient.
  • A diverging diamond interchange is cost-effective to construct and has less impact on local residents compared to a traditional interchange because it requires a smaller footprint
  • The Strathpine Road and Gympie Arterial Road diverging diamond interchange will be the second in Queensland, with the Caloundra Road and Bruce Highway (QLD) diverging diamond interchange being the first.

Funding

The Australian Government, under the Urban Congestion Fund, has committed to jointly fund (50:50) $30 million for the Gympie Arterial Road and Strathpine Road interchange upgrade with the Queensland Government.
