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

Roads and public transport investment aren’t ‘either-or’ options. Roads, rail, light rail, ferries and buses are all part of the transport solution.

WestConnex is just one of more than 80 projects outlined in the NSW Long Term Transport Master Plan to address the state’s complex transport needs. It is a critical part of all of these integrated strategies to tackle congestion and increase productivity for a growing city.

Not all trips in Sydney can be undertaken by public transport. By 2036, more than 70 per cent of the proportion of increased travel demand in Sydney will be by car. By 2036, 45 per cent of public transport will be via bus services, which rely on the road network.

The NSW Government is investing $41.5 billion (2016–17 NSW Budget) in transport projects during the next four years. This includes both roads and public transport – upgrading the bus fleet, and building the CBD and South East Light Rail, Sydney Metro and Parramatta Light Rail.
