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. 

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 has a distance-based tolling system, like the existing M7 Motorway. Motorists pay only for the sections of the motorway they use and a maximum cap applies.

Tolls will be introduced as each section of WestConnex opens to traffic. The new M4 opened to traffic in July 2017, and distance-based tolls commenced in August 2017. 

Distance based tolling will begin on the M5 East and the New M5 when the New M5 opens to traffic in early 2020.

Cars will pay one third of the heavy truck toll, reflecting the greater wear and tear trucks have on the motorway (an approach that is consistent with other Sydney motorways).
