New and significantly improved sections of motorway delivered as part of WestConnex will be tolled as they progressively open to traffic between mid-2017 and 2023. Visit the tolls page for more information.
The first major part of WestConnex is now open - the new M4 between Parramatta and Homebush, which will provide motorists with better access ramps, new smoother road surfaces and extra lanes in each direction. Distance-based tolls apply on the new M4. More than 80 percent of the M4 - between Emu Plains and Parramatta - remains free.
We are building a New M5 which will help almost halve average travel times on the current M5 East and double average travel speeds during peak times. We are also upgrading the M5 East and a toll will be introduced on this motorway to account for the massive improvements in travel time and reliability motorists will experience once the WestConnex New M5 is opened.
To maintain access to Sydney Airport’s International Terminal, trips using Marsh Street ramps will remain toll free.
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.
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).
For the current toll estimates, see Using WestConnex.
Sydney Motorway Corporation's (SMC) Community Connections Program includes the SMC Community Grant Scheme, which provides grants of up to $10,000 to local groups such as such as schools, sporting associations and social enterprises located in and around the WestConnex project area.
Grant applications are assessed against guidelines, which consider areas including community legacy, connecting communities, building capacity and helping people.
