Regional North-South Freight Route Upgrade
About the project
The Department for Infrastructure and Transport (the Department) will be undertaking works to upgrade the established Regional North-South Freight Route between Sedan and Murray Bridge to improve safety for road users, freight productivity, efficiency and network reliability.
This $12 million package of works is jointly funded (80:20) by the Australian and South Australian governments as part of the Road Infrastructure Stimulus Package.
The first stage of the project was completed in early 2021, and involved 39 kilometres of shoulder sealing works between Sturt Highway and Murray Bridge to improve safety along the route.
The second stage of the project involves works to widen and strengthen three road bridges along the route at Reedy Creek Bridge (Mannum Road, north of Murray Bridge), Marne River Bridge and Saunders Creek Bridge, (both on Ridley Road, south of Sedan).
These bridge upgrades will increase the width of the bridges, giving oversize vehicles a viable alternative to using the South Eastern Freeway and improving freight productivity in regional South Australia.
Barrier upgrades and shoulder resealing works will also be undertaken as part of stage two works at three further locations along Ridley Road, at Pine Hut Creek, Boundary Creek and Milendella Creek.
Stage two site establishment works are currently underway at Marne River, Reedy Creek and Saunders Creek Bridge. Major works are expected to commence from mid-September 2021. The works notification can be found here.
The project is scheduled for completion early 2022.
Please take extra care when workers are on site. Observe signage and speed limits, lane restrictions and traffic controllers when travelling through the area.
Motorists should expect delays, so please plan ahead and allow additional travel time.
The Department appreciates your patience and cooperation while these important works are undertaken.
