Upon completion crews will have tunnelled over 24 kilometres, with three levels of tunnels in some parts of the project.
Around 640,000 cubic metres of concrete and 32,000 tonnes of Australian steel are expected to be used on the project.
Premier Gladys Berejiklian said more than 9000 workers have worked on this stage of the WestConnex project, which also includes the Iron Cove Link.
“The NSW Government is committed to investing in major road infrastructure projects because we know improving our road network makes a real difference to people’s lives, while also providing much needed local jobs at a time when we need them most,” Berejiklian said.
“The Rozelle Interchange is the missing link in the WestConnex Project and, along with the M4-M5 tunnels, will provide connections to the City West Link and the future Western Harbour Tunnel, while also bypassing Victoria Road.”
Minister for Transport and Roads Andrew Constance said while tunnelling continues underground, plans to transform the old Rozelle Rail Yards into a park are coming to life.
“We know construction of the Rozelle Interchange is having a big impact on local residents and we thank them for their patience,” Constance said.
“When the project is finished, the new Rozelle Parklands will have green fields for leisure activities, a boardwalk, picnic areas, play equipment, and new pedestrian and cycling paths.
He said 10 hectares of public parkland and open space will transform the Inner West.”
The Rozelle Interchange is on schedule to be complete in late 2023.
