South Australian Regional Bridge Upgrades
We are upgrading a series of bridges and culverts across South Australia to improve safety for road users and increase productivity and efficiency for the freight industry.
These works are being delivered as part of the following funding packages:
- South Australian Rural Roads Package, jointly funded by the Australian and South Australian governments
- Bridges Renewal Program, jointly funded by the Australian and South Australian governments
- Bridge Stimulus Package, funded by the South Australian Government.
Works have been undertaken across multiple locations in South Australia, with majority being completed in 2023. Works on the bridge over Junction Creek on Onkaparinga Valley Road (Balhannah) are expected to be completed by late September 2024.
