As part of the Node Plan, the new state of government hopes to make some changes to Sydney's roads, which will help ease traffic pressure on some of the city's most congested streets.
The $1 billion plan involves 36 projects under construction or about to be built.
The Great Western Highway upgrade at the Marsden St junction in the Parramatta district is expected to be completed this month.
By then, an east-left lane will enter Marsden St, turn west, turn right, and extend to Pitt St, where traffic lights are almost replaced on the highway at the intersection O'Connell St and Marsden St.
The Great Western Highway project at the Blacktown Rd junction in the Prospect district will be completed in September.
Construction of Stacey St and Fairford Rd will begin in the next few weeks in Bankstown, including the expansion of the Stacey St southbound road from two lanes to three lanes, and the expansion of the Stacey St double right turn lane to Macauley Ave.
During the rush hour, thousands of cars were always on the road, and long, frustrating queues lined up.
The revamping works are aimed at easing the situation, and the state government hopes to cut traffic times by 30%.
"We want to improve people's travel time so they can spend more time with their families," said Melinda Pavel (Melinda Pavey), the highway director.
From now until March 2019, more congestion management projects will be launched in Kirrawee,Carlingford,Lane Cove West,Burwood,Five Dock and Parramatta.
