Building the first WestConnex tunnel is set to begin within months

Sophia Rostron   |   February 14, 2016

Building the first WestConnex tunnel is set to begin within months, with planning approval received for the new underground M4 East, an important step in the crucial project. Federal Minister for Major Projects Paul Fletcher said the tick of approval from the NSW Department of Planning and Environment meant initial works could begin straight away on the 5.5km tunnel, with major construction expected to start in the middle of the year.

M4 East

M4 East works are part of Stage One (WestConnex M4 - Parramatta to Haberfield) of the WestConnex project.

Due to open to traffic in 2019, the M4 East will extend the existing M4 Motorway from Homebush to Haberfield, reducing congestion at the end of the M4, saving travel time for motorists and removing cars from local streets. It will also bypass Parramatta Road and connect to City West Link.

The project is predicted to accommodate an estimated 67,700 vehicles each day through 5.5 kilometre tunnels with three lanes in each direction by 2021.

The M4 East extension is in addition to the works currently underway to widen the existing M4 Motorway to four lanes in each direction from Church Street, Parramatta to Homebush Bay Drive, Homebush.

Some key benefits of the M4 East project include:

  • connecting to M4 East at Concord Road
  • improving access to the existing M4 at Homebush Bay Drive, increasing reliability for through traffic
  • removing an estimated 3,000 trucks each day from Parramatta Road
  • providing new, wider footpaths, street landscaping and other surface road improvements for local residents at Patterson Street, Concord and Wattle Street, Haberfield
  • connecting to Parramatta Road, Ashfield and to City West Link (Dobroyd Parade), Haberfield
  • including ramps on Wattle Street for a proposed M4-M5 Link.


Planning Approval

Planning approval for the M4 East tunnel followed a robust EIS assessment process that considered submissions from the community and business. Construction will generate more than 2,500 direct jobs alone, and employ more than 100 apprentices or trainees, with the project adhering to strict air quality standards.

Another milestone was reached last week with the planning application lodged for the final stage of WestConnex, the tunnel joining the widened and extended M4 and the M5 Motorway. Read more about this step with a previous post of ours - WestConnex Stage 3 (M4-M5 Link) planning underway

The local community has already benefited from new world-class hockey facilities built at St Lukes Park at Concord to allow nearby Cintra Park to be used as the midway tunnelling point for the M4 East.

Significance of planning approval

"This is another WestConnex milestone and, once finished, the tunnel will allow motorists to travel between Homebush and Haberfield without stopping at a single traffic light," Mr Fletcher said.

NSW Minister for Roads Duncan Gay said this step of the project included a focus on easing congestion on notoriously clogged Parramatta Road, with the government exploring options to improve public transport.

"I don't want motorists to lose any more time sitting in the car park that is Parramatta Road, and WestConnex will be crucial in fixing the problem," Mr Gay said.

As a result of WestConnex, predicted traffic volumes on sections of Parramatta Road are expected to be cut by up to 53 per cent in 2021. By 2031, predicted truck numbers on Parramatta Road east of Concord are expected to be cut by 10,000 a day.

The M4 East will join the widened M4 at Homebush and extend underground through a tunnel with three lanes in each direction, and exit ramps at Parramatta Road and the City West Link.

Motorists driving along the M4 between Parramatta and Homebush are already seeing extensive work taking place to widen that part of the motorway, which is the first section of WestConnex.
