Westconnex M4 East

This project by has achieved a 'Leading' As Design v1 IS Rating.


The M4 East will extend the existing M4 Motorway with two new 5.5 kilometre tunnels, three lanes in each direction, from Homebush to Haberfield. The extension will reduce the bottleneck at the end of the M4, saving travel time for motorists and removing cars from local streets. It will provide a bypass of Parramatta Road and a connection to the City West Link.

The M4 East connects to work already underway on Stage 1, the widening of the existing M4 Motorway to four lanes in each direction from Church Street, Parramatta to Homebush Bay Drive, Homebush.
