Gundagai Rail Viaduct
Project overview
Transport is working to implement measures to ensure the ongoing safety of the Rail Viaduct in the short to medium term. We are also working to develop a long-term strategy for the Viaduct as part of Transport's Regional Rail Heritage Strategy.

Project information
Background
Built in 1903, the Gundagai Rail Viaduct is a Howe timber truss bridge which sits next to the site of the former road bridge and is an impressive 819.4 metres long. This viaduct serviced the Tumut area for 82 years and is listed on the state heritage register. The non-operational viaduct holds cultural and historical significance for the community and key stakeholders.
The maintenance of this viaduct is managed by UGL Regional Linx (UGLRL) on behalf of Transport. Transport continues to work with UGLRL to ensure public safety at Gundagai Viaduct.
Between November 2022 and July 2023, the following safety measures were installed to address the immediate risk of falling debris such as loose bolts or timber sleepers:
- a covered pedestrian walkway over the pedestrian path adjacent to Middleton Drive
- monitoring cameras at Middleton Drive and OI Bell Drive at the intersection of the Viaduct
- concrete bollards at Middleton Drive and OI Bell Drive at the intersection of the Viaduct
- the closure of the track under span 25 adjacent to OI Bell Drive (previously used by high-sided vehicles accessing the showground)
- repair of flood-damaged fencing between OI Bell Drive and Middleton Drive
- additional fencing at Morleys Creek and adjacent to the golf course
- free-standing portal netting structure over Middleton Drive and OI Bell Drive.
UGLRL carries out regular inspections of the Rail Viaduct to ensure public safety.
Next steps
Transport and UGLRL are currently investigating the potential to install steel supports at both Middleton Drive and OI Bell Drive to further improve public safety.
We are seeking advice from engineering experts to confirm the nature and extent of the steel supports required.
Transport will update the community and stakeholders before work starts to install the supports.
Regional Rail Heritage Strategy
The long-term future of the Gundagai Viaduct will be informed by Transport's Regional Rail Heritage Strategy (Strategy), which is currently under development.
The purpose of the Strategy is to identify priorities for conservation across the timber underbridge asset class and provide recommendations for the ongoing management of regional rail heritage assets.
A draft Strategy will be available for public consultation, pending endorsement by the Heritage Council of NSW.
We will keep you informed as our work progresses and provide more information on the public consultation process for the Strategy.
Community information
Engagement approach
Transport is committed to keeping the community and stakeholders informed of project progress and the consultation process. We will do this using a variety of communication channels such as email, community notifications, social media, and our project website.
Community consultation
We will provide more information on the public consultation process for Transport's Regional Rail Heritage Strategy as it becomes available.
