WestConnex projects will open to traffic in stages between 2017 and 2023. See our Interactive map

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. 

WestConnex is generating more than 18 hectares of new open space for communities in the inner west. 

We sometimes use parks and other government-owned land during construction. This helps us to avoid the acquisition of private property. When we use green space during construction, we always try to return it for community use when construction is finished.
