Delivering WestConnex: M4 widening work approved to start

9 January 2015

Federal Assistant Infrastructure Minister Jamie Briggs and NSW Roads Minister Duncan Gay today announced preparatory work will start in a fortnight on the $500 million WestConnex M4 Widening.

“This is another important milestone in building WestConnex which will create 10,000 jobs and deliver more than $20 billion in economic benefits to New South Wales,” Mr Briggs said.

“WestConnex will transform Sydney by fixing the M4 and M5 and joining them together in a continuous free flowing motorway connecting to Sydney’s CBD, Airport and Port.

“This world class infrastructure project will cut 40 minutes from a typical journey between Parramatta and Sydney Airport, bypassing up to 52 sets of traffic lights.

“It will deliver better roads and slash travel times for motorists, meaning less time stuck in traffic and more time at home with the family or being productive at work,” Mr Briggs said.

“With planning approval now granted, preparatory work will begin along the corridor later this month including final geotechnical work and investigation of utilities before site work gets underway in February,” Mr Gay said.

“The Rizzani De Eccher Leighton joint venture has been contracted to design and construct the 7.5 kilometre project, due for completion in early 2017.

“It will target congestion on one of Sydney’s major motorway corridors and cut travel times by up to 74 per cent on this section of the M4.”

"The project will widen the M4 Motorway to four lanes in each direction between Parramatta and Homebush and include ramp upgrades such as new direct access from Homebush Bay Drive to the M4 westbound, removing a well known pinch point.

“In addition, a new M4 connection for motorists heading eastbound from Hill Road will be built, supporting the growth around Sydney Olympic Park.

“Once major construction gets underway, most of the work will be taking place behind safety barriers or separate to the current motorway lanes, reducing the impact on motorists,” Mr Gay said.

The NSW Government is providing $1.8 billion worth of funding for WestConnex and the Australian Government $1.5 billion, in addition to a concessional loan of up to $2 billion to fast-track Stage 2 of WestConnex from Beverly Hills to St Peters.
