Twin tunnels from Haberfield to St Peters could be built as a standalone project by 2022, and initially operate independently from the Rozelle Interchange and Iron Cove Link.
New design features for the next stage of WestConnex have been released, showing:
- potential for the M4-M5 Link twin tunnels to be completed early as a standalone project
- tunnel capacity increasing from three to four lanes in each direction
- exit and entry ramps at Camperdown removed.
The new design will help to significantly reduce traffic on Parramatta Road between Haberfield and the CBD.
The tunnel alignment will move west to a more direct route between the Rozelle and St Peters interchanges. This will not impact Royal Prince Alfred Hospital and its Cyclotron medical research facility or the University of Sydney.
No further residential properties are required for the M4-M5 Link. A small number of commercial properties will need to be acquired for a tunnelling site on Parramatta Road at Camperdown.
The community will have the opportunity to have their say when the M4-M5 Link Environmental Impact Statement is released in 2017.
