Overview
The Department of Transport and Main Roads (TMR) is upgrading the Cunningham Highway and Ipswich-Rosewood Road intersection.
This intersection provides the main access point to Australia’s largest operational military air base – the Royal Australian Air Force (RAAF) Base Amberley. Traffic flow rates exceed the capacity of the intersection, resulting in significant travel delays.
The project's business case has identified two design options to improve safety and efficiency for motorists, interstate and inter-regional freight vehicles, bike riders and pedestrians, and to service the high demands of the RAAF Base Amberley.

Design 1
Design 1
Scope of works
- Remove the existing priority intersection at Cunningham Highway and Ipswich-Rosewood Road and install a roundabout
- Remove the existing four-way intersection at Heit Street, Ipswich-Rosewood Road and Southern Amberley Road and install a new roundabout to the north of the existing intersection
- Remove access to Oneills Road and Heit Street from Ipswich-Rosewood Road
- Duplicate the Cunningham Highway bridge at Warrill Creek crossing.
Benefits
- Ability to alter traffic signal timing to cater for varying traffic demands at new mainline roundabout
- Improved motorist safety and reduced likelihood and severity of crashes
- Capacity to cater for growth in the region
- Safer connections between communities due to improved controls on traffic demands.
