Fairfield mayor Frank Carbone said roundabouts will help improve safety at two notoriously busy intersections in Fairfield.
Roundabouts have just been completed at the intersections of Granville and Smart streets in Fairfield Heights and Melbourne Road and Canberra Street in St Johns Park.
Mr Carbone said each of the roundabouts will improve traffic flow as well as significantly lessen the chance of crashes.
"Turning in and out of these streets will now be a lot easier and less frustrating for motorists," he said
"Road safety is one of council's priority concerns. Investment in road infrastructure is an investment in our community's safety.
"We want families to be able to return home safely each day without injury or expensive vehicle repairs."
Mr Carbone said council is investing almost $13 million this financial year to maintain and improve 23 kilometres of the local road network to make it "safer and more efficient."
In the next few months a roundabout will also be installed at Avoca and Humphries roads, Wakeley.
