We’re upgrading the intersection of Donnybrook Road and Mitchell Street to reduce travel times, improve safety, cater for population growth and increased vehicle movements.
The upgrade will:
- replace the existing roundabout with traffic lights
- build a new bridge over Kalkallo Creek
- add extra lanes at the intersection
- install safety barriers.
Planning update
Planning work is progressing as the upgrade moves towards construction. Key activities include:
- detailed traffic analysis and modelling, to better understand the future growth of the area and the demand this will place on the road network
- on-site investigations to test ground conditions
- environmental investigations to understand flora, fauna and tree species
- investigations to map utility services above and below the ground
- developing detailed project designs for construction.
Initial planning work is expected to be complete in late 2025. Construction timelines will be known once our planning has progressed further.
Community feedback
From 23 June to 13 July 2025, we asked for community feedback to help inform our planning.
