We have delivered this upgrade to the interchange at Strathpine and Gympie Arterial Road. I get a lot of questions about this intersection so check this map out below, or the below link for more details on the design.
When Bald Hills residents were telling me how congested and dangerous this intersection is, we listened and took action.
Innovative Diverging Diamond Design
The design has transformed the interchange into a diverging diamond – an innovative intersection design that has reduced congestion, improved travel times and addressed safety concerns.
The new interchange, while unfamiliar to Australian drivers, has proven to be easy to navigate, aided by out engagement with road users to help drivers understand how to navigate the intersection.
Construction for the interchange was completed in August 2022 with finalisation works continuing through 2023.
Benefits
- Improved safety
- Increased capacity
- Reduced travel time
- Reduced peak hour congestion
- Contributed to economy
- Contributed 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.
- The diverging diamond interchange was 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 was 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, jointly funded (50:50) $30 million for the Gympie Arterial Road and Strathpine Road interchange upgrade with the Queensland Government.
