The NSW Government released the concept design for M4-M5 Link, which is the final stage of WestConnex. 

Premier Gladys Berejiklian said that the M4-M5 Link would “bridge a major gap in the road network, creating a non-stop underground western bypass of Sydney’s CBD with links to the port and airport precincts”.

“This is the most critical section of WestConnex and the most beneficial in that it will slash travel times, as well as significantly constrain traffic growth on Parramatta Road,” she said.

According to Transport for NSW, WestConnex will enable drivers to save around 20 minutes during a peak hour trip between Burwood and Sydney Airport, while up to 40 minutes may be saved during a journey between Parramatta and Sydney Airport. 

Also, drivers will save around 30 minutes during a morning peak hour trip from Port Botany to Silverwater. 

Further, it is expected that up to 10,000 fewer trucks will be on Parramatta Road east of Concord after completion. 

Minister for WestConnex Stuart Ayres said the Government have “listened to the community, and we are now seeking further feedback and ideas to refine the project’s design ahead of the Environmental Impact Statement which will be released mid-year”. 

“The M4-M5 link will form a key part of Sydney’s road network by connecting to projects like the future Western Harbour Tunnel and F6 extension while also improving the liveability of local communities,” he added.

Moreover, the NSW Government announced the implementation of tolling on the new M4 after a one-month toll-free period. 

On the new section of the M4 between Parramatta and Homebush, a distance-based toll of between $1.77 and $4.56 will be implemented.
