Two changes are proposed to upgrade the intersection of President Avenue and Gymea Bay Road, Gymea.
The southern side of President Avenue will be widened to provide a dedicated left turn bay into Gymea Bay Road southbound.
The existing right turn lane from President Avenue into Gymea Bay Road northbound will be extended.
Miranda MP Eleni Petinos and Cronulla MP Mark Speakman said the work was expected to start later this year.
An upgrade of the intersection was promised before the last state election in March, 2015.
Roads and Maritime Services (RMS) has been working with Sutherland Shire Council on the design for the intersection, which handles 40,000 traffic movements a day, with congestion occurring in the morning and afternoon peak periods.
The improvements will be delivered under the state government’s $100 million Congestion and Safety Program.
