Haberfield/Ashfield Option B

If Option B is selected, the sites outlined below would be utilised. However, some work would still need to be undertaken below ground at Wattle Street interchange.  

In this case, there is potential to use the Wattle Street site outlined in Option A for tunnelling and tunnel support only.  The construction area at the surface between the Wattle Street carriageways would not be needed for M4-M5 Link construction purposes. This would be confirmed as part of detailed construction planning.

Parramatta Road West civil and tunnel site

  • The Parramatta Road West civil and tunnel site would be located west of Parramatta Road between Alt Street and Bland Street at Ashfield.
  • The site would be used for tunnelling support during construction and would include temporary site offices, a workshop, amenities and storage facilities; a temporary substation; temporary ventilation for the tunnels; a temporary acoustic shed; a temporary water treatment plant; and car parking.
  • No permanent facilities would be constructed at this site.
  • Key construction activities would include site establishment and utility works, tunnelling, and civil and mechanical fitout.
  • Roadheaders would be launched from this site and would excavate the temporary access tunnel, mainline tunnels and Wattle Street interchange entry and exit ramps.

Access routes

  • Construction traffic would enter and exit the site to and from the western (northbound) carriageway of Parramatta Road via new driveways.
  • It is anticipated that 140 heavy vehicles and 10 light vehicles would enter and exit the site each day

Further details on proposed construction activities at the Parramatta Road West civil and tunnel site are outlined in Chapter 6, Section 6.5.5 of the EIS.

Parramatta Road East civil site

  • The Parramatta Road East civil site would be located east of Parramatta Road at Haberfield between Alt Street and Bland Street. The site is currently occupied by several commercial premises. 
  • The Parramatta Road East civil site would be used to support tunnelling construction activities at the Parramatta Road West civil site, and to provide construction workforce parking.
  • Key construction activities that would take place at this site include site establishment and utility works; and the establishment of around 140 car parking spaces.

Access routes

  • Light vehicles would enter and exit the site via Alt Street and Bland Street.
  • It is anticipated that 30 heavy vehicles and 150 light vehicles would enter and exit the site each day

Further details on proposed construction activities at the Parramatta Road East civil site are outlined in Chapter 6, Section 6.5.7 of the EIS.

 

Haberfield civil site

  • The Haberfield civil site is an alternative design to the Haberfield civil and tunnel site outlined under Option A, but in the same location (by the south-eastern corner of the Parramatta Road and Wattle Street intersection, extending along Parramatta Road between Wattle Street and Walker Avenue).
  • The Haberfield civil site would predominantly be established to support fitout of the Parramatta Road ventilation facility (which is being built by the New M4 project) and construction of a substation. This civil site would not be used to support tunnelling.
  • Other key construction activities that would take place at this site include initial road works and traffic management; site establishment and utility works; and landscaping.
Access routes
  • Heavy vehicles delivering materials and equipment would enter and exit the Haberfield civil site via the westbound Wattle Street carriageways. Light vehicles would enter and leave the site via Wattle Street and Walker Avenue.
  • It is anticipated that 10 heavy vehicles and 20 light vehicles would enter and exit the site every day.

Further details on proposed construction activities at the Haberfield civil site are outlined in Chapter 6, Section 6.5.6 of the EIS.
