City of Onkaparinga will impose a 40km/h speed limit in Old Noarlunga township from December.

The decision follows requests from local residents for a reduction of the speed limit from 50km/h to 40km/h to improve pedestrian safety.

A review of the road network in Old Noarlunga cause the council to confirm that Patapinda Road and the other local roads within the township are well suited to a 40km/h speed-limited area.

The township has an enclosed road network with one entry point from Main South Road and one entry point just south of the Church Hill Road and Patapinda Road intersection.

The council says reducing the speed limit to 40km/h will improve pedestrian and cyclist safety on Patapinda Road and other locations, including:

• Market Square Reserve, the Noarlunga Institute and Winnaynee Horse Inn Reserve.
• Old Noarlunga Primary School’s crossing for children walking and riding to and from school.
• Noarlunga Football Club, Tennis Club and the playground at the Noarlunga Recreation Ground.
• The Old Noarlunga Hotel, hairdressers, cafés, shops and other businesses.
• Pedestrians accessing bus stops.
• The narrow bridge over the Onkaparinga River.
• The pedestrian refuge near Main South Road.

Extending the reduced speed limit throughout the Old Noarlunga township aims to provide a consistent speed limit for all road users and improve road safety for visitors and residents.

The council says the change will result in a small increase of approximately 19 seconds additional travel time on Patapinda Road, following practical drive through assessments. 

Signage to indicate the new 40km/h speed limit will be installed before it comes into effect in December.

Onkaparinga Council  says it will closely monitor the effectiveness of the change during 2025.
