We fully recognise the importance of Sydney Park and the investments that the City of Sydney Council and others have made in recent years.
A strip of land owned by Roads and Maritime Services adjacent to Sydney Park is being used to widen Euston Road as part of local road upgrades. This is not part of Sydney Park.
As outlined in the City of Sydney’s own management plan for Sydney Park, this land is dedicated road space and has been subject to a long-standing road widening reservation.
A small boundary strip, adjacent to the road reserve, is also required for the local road widening, however this is more than offset by the additional 8.5 hectares of open green space being created at St Peters Interchange.
Two hectares of this open green space will be directly connected to Sydney Park via a land bridge over Campbell Road.
Traffic modelling tells us the expected demand for WestConnex and the number of traffic lanes needed. The motorway has been designed to meet traffic demand now and in the future.
The number of lanes varies across the project:
- M4: we are widening the M4 Motorway from three lanes in each direction to four lanes in each direction between Parramatta and Homebush. The new M4 East tunnels between Homebush and Haberfield will be three lanes in each direction.
- New M5: when the tunnels open, there will generally be two lanes in each direction between Kingsgrove and St Peters. The tunnels can accommodate three lanes in each direction in future, with additional approvals needed for this change.
- M4–M5 Link: The M4-M5 Link will provide twin underground tunnels with four lanes in each direction between Haberfield and St Peters.
For surface road sections of the motorway, including the widened M4, the speed limit will generally be 90km/h. In tunnels, the speed limit will be 80km/h, the same as for other tunnels in Sydney. A small section connecting to Sydney Airport may have a lower speed limit.
