The Hume Highway (Sheahan Bridge) upgrade proposal seeks to address a key constraint on the Hume Highway, one of Australia’s busiest and most important freight corridors. The proposal aligns with the Infrastructure Policy Statement’s priority to strengthen nationally significant supply chains by improving the resilience and reliability of key freight corridors. It also supports the objectives of the National Freight and Supply Chain Strategy, which calls for improved efficiency, safety, and competitiveness in domestic supply chains. The northbound bridge is the last bridge capacity restriction to allow larger and more efficient High Productivity Vehicles (HPVs) on the Hume Highway between Sydney and Melbourne. The Sheahan Bridge is also a critical component of the freight network between Sydney and Adelaide.
PROPOSAL DESCRIPTION
The Hume Highway (Sheahan Bridge) upgrade involves replacing the existing northbound bridge at Gundagai to enable unrestricted HPV access, improve freight efficiency, and support national supply chain resilience.
INVESTMENT RECOMMENDATION
The Australian Government should note this proposal as a potential future investment opportunity within the 2-4 year pipeline. The Australian Government has committed $16 million for planning activities, including scoping and design of the proposed upgrades.
OPPORTUNITIES AND OUTCOMES
This proposal has the potential to:
- Unlock national freight productivity – removing the final bridge restriction on the Hume Highway would improve freight efficiency by allowing more freight to be moved with fewer vehicles.
- Enhance safety – the upgrade would enable the use of HPVs with advanced safety features, reducing crash exposure and improving safety for all road users.
- Reduce transport emissions – enabling HPVs would improve freight efficiency by reducing heavy vehicle kilometres for a given freight task, supporting a reduction in carbon emissions and fuel consumption.
- Improve supply chain reliability and resilience – an upgraded bridge structure would support more consistent freight movements and reduce maintenance-related disruptions.
NEXT STEPS
Proponent to progress planning activities (in line with Infrastructure Australia’s Assessment Framework).
