Major work on the M5 West Widening project commenced in August 2012. The project will expand the South West Motorway from two to three lanes in each direction generally from Camden Valley Way to King Georges Road. This will reduce travel time for motorists using the motorway and surrounding roads and support planned residential and employment growth in south west Sydney.

The $400 million widening project will be primarily funded by Interlink Roads with the NSW Government contributing $50 million towards the cost of new and improved noise walls and individual noise treatments at more than 200 properties.

The project will support up to 500 jobs and is expected to be completed in late 2014. For detailed information about construction work and traffic changes please visit the M5 West Widening website.

What's happening now - June 2013

• Widening work is now underway along the length of the M5 South West Motorway.
• 5 kms of unsurfaced pavement has been laid in the median.
• Work is underway to construct 9 of the 23 new sediment basins along the motorway corridor.
• Work is underway to construct new noise walls and heighten existing noise walls. As part of the upgrade, approximately 6 kms of new noise walls will be constructed and approximately 12 kms of noise walls will be heightened.
• Work is underway to widen the Queen Street Bridge at Revesby and the Nuwarra Road Bridge at Hammondville (the motorway passes over Queen Street and Nuwarra Road at these locations). Work at each bridge will take approximately 6 months and includes boring piles, installing girders and pouring a new deck to connect the new extension to the existing bridges.

Ongoing work

• Vegetation clearing
• Sediment basin construction
• Excavation and stabilisation work in the median
• Constructing new noise walls and heightening some existing noise walls
• Service relocation work

Some of this work requires lane closures and will be undertaken at night when traffic volumes are lower.
