The Federal and NSW governments are progressing plans to upgrade Sheahan Bridge on the Hume Highway at Gundagai, aiming to improve freight access and road safety.
The $20 million jointly funded planning project has entered its next phase, with WSP Australia awarded the contract to develop a concept design and conduct environmental assessments for either upgrading or replacing the northbound bridge over the Murrumbidgee River.
Built in 1977, the existing northbound bridge had its load limit increased from 68 to 85 tonnes in 2020. However, Higher Productivity Vehicles still require permits to travel on the NSW section of the Hume Highway due to structural limitations. These constraints also restrict contraflow options during emergencies or maintenance on the southbound bridge.

The Sheahan Bridge Upgrade planning project will explore three potential solutions: constructing a new bridge upstream or downstream of the existing structure, replacing the current bridge on its existing alignment, or strengthening the existing bridge.
NSW Labor spokesperson for Cootamundra, Stephen Lawrence MLC, welcomed the project’s progress, stating he looks forward to seeing the preferred option.
Transport for NSW is now working with the contractor to assess each alternative, with a preferred option expected to be released for public consultation in mid-2026.
