Gore Highway (Millmerran – Goondiwindi), Wyaga Creek, upgrade floodway
The new bridge over Wyaga Creek at Kilbronae has improved flood immunity, safety and efficiency on the Gore Highway between Millmerran and Goondiwindi, which is one of Queensland's most important transport links.
The Gore Highway is part of the National Land Transport Network and is a critical link for inter and intrastate travel in Queensland.
A 2016 flood study of the Gore Highway between Westbrook and the Leichhardt Highway identified Wyaga Creek crossing at Kilbronae as the largest contributor to the annual average flood-related closure time at 44 hours.
The new bridge has raised the crossing by 1.44m to significantly reduce the annual average closure time of the Gore Highway.
