Gympie Arterial Road and Strathpine Road (Bald Hills), improve intersection
Construction is underway to address safety and congestion concerns at the Gympie Arterial Road and Strathpine Road interchange at Bald Hills.
The project design will transform this interchange into a diverging diamond interchange (DDI), an innovative intersection design that will reduce congestion, improve travel times and improve safety.
The new DDI is the third of its kind in Queensland and while unfamiliar to many drivers, will be easy to navigate. TMR will engage with road users to help them understand how to navigate the intersection.
The local community will be kept informed as the project progresses.
- Improves safety
- Increases capacity
- Reduces travel time
- Reduces peak hour congestion
- Contributes to economy
- The new innovative diverging diamond interchange (DDI) system allows free flowing turns when exiting and entering Gympie Arterial Road.
- The interchange reduces the number of conflicts with opposing traffic on Strathpine Road resulting in less traffic signal phases, making the interchange safer and more efficient.
- A DDI is cost-effective to construct and has reduced impacts on local residents compared to a traditional interchange because of its smaller footprint.
- The Gympie Arterial Road and Strathpine Road diverging diamond interchange will be the third in Queensland, behind the Caloundra Road and Bruce Highway and the Pacific Motorway (M1) Varsity Lakes to Burleigh DDIs.
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. Investment ID 703296
