City of Onkaparinga plans to install a roundabout to improve safety at the intersection of How Road and Aldinga Beach Road.

The planned works involve reconstructing the intersection and increasing its capacity to cope with extra traffic flows from nearby developments and the Aldinga Payinthi College. 

The new dual lane roundabout will be similar to one further west at the Aldinga Beach Road and Rowley Road intersection. 

The council says a roundabout is the best solution for improving safety and reducing congestion.

The draft concept plan can be viewed on the council website.

Preparatory work is almost complete and major construction is expected to start in October.

How Road South will be closed for the duration of the project and traffic management will be in place to maintain safety for workers and the community.

The project is scheduled to be completed in the 2024-25 financial year.
