The Bruce Highway (Tinana interchange) project involves:
- constructing a northbound off-ramp to provide a left-hand diverge and provide a new overpass structure with both through lanes of highway traffic travelling under the new overpass
- relocating the Three Mile Road intersection about 300m south of its current location to accommodate the new northbound off-ramp and maintain safe turning movements at the intersection
- removing the southbound off-ramp to Gympie Road due to poor geometry and constructing a new southbound off-ramp to Iindah Road to cater for southbound traffic
- upgrading the existing southbound on-ramp to improve the merge with the highway by constructing a longer acceleration lane and improving visibility
- incorporating a wide centre line treatment to provide greater separation of opposing directions of traffic.
The project also includes installing traffic signals at the Gympie Road and Iindah Road West intersection at Tinana. Dedicated right-turn lanes will be provided on Gympie Road to improve traffic efficiency. All pedestrian movements will be controlled by the signals which can be activated by push buttons. Pram ramps will be installed and will include tactile ground surface indicators to assist the visually impaired. These works are expected to occur towards the end of the project.
