Case study Better connections for wildlife, Logan Enhancement Project

The Logan Enhancement Project is a $512 million project to reduce congestion and improve motorist, cyclist and pedestrian connectivity on the Logan and Gateway motorways in Queensland. It's located within an ecologically significant region, and to reflect this, we adopted the theme "A Forest Drive". This theme is evident in the integration between road, shared bike and pedestrian trails and fauna connectivity. The shared trail ensures the community will have access to the area’s natural beauty, while dedicated and enhanced fauna overpasses and underpasses will ensure local wildlife can cross the road safely. The fauna land bridge at Illaweena Street is a good example of the project’s focus on fauna connectivity and biodiversity enhancement. The bridge will provide critical connectivity for vulnerable fauna such as koalas and gliders. Images of local wildlife have been added to the bridge, giving motorists insight into the bridge’s purpose. The "Forest Drive" aesthetic extends into bridge structures, anti-throw screens, retaining wall parapets and noise barriers—these all connect with the landscape design and natural landscape beyond, celebrating the area’s unique qualities, while also ensuring low- maintenance requirements.

Case study Noise management on the Logan and Gateway motorways

Residents living near the Logan and Gateway motorways (Queensland) have the benefit of 13 new noise barriers built at key locations along these busy motorways. All up, we built 3.6km of new precast concrete noise barriers. These were painted a eucalypt green to blend in with the natural surroundings and improve visual amenity for landowners and motorists. The new noise barriers, part of our $8 million Noise Management Program, are significantly reducing noise levels generated by motorway traffic for local residents.
