'Missing' motorway link hits major milestone
Half of the tunnelling on the critical M4-M5 Link Tunnels has now been completed, marking a major milestone on ‘the missing link’ in Sydney’s motorway network.
Premier Gladys Berejiklian said work on the M4-M5 Link Tunnels is progressing well, and is on track for the project to open on schedule in 2023.
“More than 6800 workers have been involved in the project to date, providing valuable jobs when we need them most.
“Along with the Rozelle Interchange, this project will allow drivers to experience the full benefits of the WestConnex motorway network, Australia’s biggest road infrastructure project,” Ms Berejiklian said.
The M4-M5 Link Tunnels connect the M4 at Haberfield with the M8 at St Peters, along with connecting to future projects including Sydney Gateway to Sydney Airport, the M6, the Western Harbour Tunnel and Beaches Link via the Rozelle Interchange.
“When complete, WestConnex will change the way Sydneysiders get around their city. WestConnex will bust congestion and increase economic activity,” Minister for Roads Andrew Constance said.
“It will also give local roads back to local people, with the majority of the project underground.”
Earlier stages of WestConnex, the New M4 Tunnels (opened in July 2019) and the M8 (opened in July 2020) are providing tens of thousands of motorists with significant travel time savings since opening.
When complete, the M4-M5 Link Tunnels will provide drivers with additional travel time savings, including an estimated 40 minutes off a trip from Parramatta to Sydney Airport.
