South Australian Regional Bridge Upgrades Early Works Notification - Balhannah and Oakbank

The Department for Infrastructure and Transport (the Department) is upgrading a series of bridges and culverts across regional South Australia to extend the service life of the structures and improve safety for road users.

As part of this program, the Department for Infrastructure and Transport (the Department) will be upgrading the following bridges:

• Bridge over Junction Creek, Onkaparinga Valley Road, Balhannah;

• Bridge over Onkaparinga River tributary, near Pugh Road, Onkaparinga Valley Road, Balhannah; and

• Bridge over Onkaparinga River tributary, near Beasley Road, Onkaparinga Valley Road, Oakbank. These works are funded by the South Australian Government as part of the Bridge Stimulus Package.

Early works, including service relocations are currently underway at the bridge over Junction Creek in Balhannah. Vegetation management and removal will be undertaken across all sites commencing from early September 2022, and are expected to be completed in September 2022, weather permitting. This work will be undertaken between 7am and 5pm, Monday to Fridays and between 7am and 3pm on Saturdays.


Impacts to vegetation have been carefully considered and will be minimised wherever practicably possible.

To safely facilitate these works, speed and lane restrictions will be in place during the works. Road users are asked to please plan ahead, allow extra travel time and take extra care when workers are on site. Observe speed limits, lane restrictions and traffic controllers when travelling through the area.

Access to properties will be maintained throughout the works, wherever possible, with advance notice provided if there is a need to temporarily restrict driveway access.

Some noise disturbance can be expected at times while these works are completed, however the work will be managed to minimise disturbance to nearby residents and businesses, as much as practically possible.

Major construction is scheduled to commence from September 2022, with project completion expected in early to mid-2023, weather permitting. Further information about the timing of works and the planned traffic management during major construction will be provided in advance of works commencing.
