WestConnex is a 33km motorway that links Sydney’s West with the airport and Port Botany precincts. The project is in response to NSW Government commitment to deliver a motorway scheme for Sydney city, as well as recommendations from Infrastructure NSW in its State Infrastructure Strategy
The project includes:
- Widening of the existing M4 motorway to four lanes in each direction for 7.5km between Church Street, Parramatta and Homebush Bay Drive, Homebush.
- Constructing ramp upgrades, including new direct access from southbound Homebush Bay Drive to the M4 westbound through a G-ramp, thus removing the need for a right turn at the traffic lights; and, eliminating a traffic pinch point and providing a new M4 connection for motorists heading eastbound from Hill Road, thus supporting the growth around Sydney Olympic Park.
- Maintaining the existing grade-separated interchanges at James Ruse Drive, Silverwater Road and Homebush Bay Drive.
- Widening the Granville viaduct and other bridges for 2.3km.
Heading and Associates were initially engaged to give survey support on the bridge structural works, but quickly moved into earthworks and pavement works as well.
