Warrego Highway–Toowoomba East Creek and West Creek: culvert upgrades

The Toowoomba East Creek and West Creek culvert upgrade projects, designed to improve community safety, accessibility and flood resilience have been completed.

The existing East Creek and West Creek culverts provided James Street with a 1-in-5-year flood event immunity. To protect against inundation at nearby intersections during high-intensity and high-velocity rainfall, as in the 2011 floods, these culverts required significant upgrades.

Now completed, these upgrades will provide better access, safety and greater flood immunity during rain events, providing access for the community to Toowoomba Hospital and other services. These upgraded culverts will integrate with the surrounding area and broader transport networks.

These works also support the infrastructure upgrades that Toowoomba Regional Council has undertaken in the Gowrie Creek catchment. When further tie-in works are completed upstream and downstream, a 1-in-100-year minimum flood immunity standard will be achieved.
