The massive Westlink M7 project is well ahead of schedule as it nears completion.

Westlink M7 is the 40 kilometre fully electronic tollway being constructed in Western Sydney. The Federal Government is contributing $356 million towards the construction of this motorway with the remainder of the cost being met by the private sector.
Beginning at the Hume Highway, Prestons in the South, the motorway intersects the M4 at Eastern Creek and the M2 at West Baulkham Hills in the North. There are a total of 17 interchanges along the 40 km motorway, which will revolutionise access to Western Sydney from Liverpool to Baulkham Hills.
Thirty-eight over- and underpasses, one hundred and forty six bridges and a 40 km cycleway and walking path are being constructed as part of the project to improve access for communities along the motorway corridor.
Motorists using the Westlink M7 will bypass up to 48 sets of traffic lights and enjoy significant time savings when travelling across Western Sydney. Westlink M7 is a free flow toll road where tolls will be collected electronically. This means motorists will enjoy a seamless journey with no slowing down or stopping for toll plazas or boom gates.
Westlink M7 will be the catalyst for further economic growth in Western Sydney.  The Westlink M7 is scheduled to open to traffic by April 2006.

This system comprises two cameras on top of a 44 metre Rocla Communications pole focused on construction of the M4-M7 "lighthorse" interchange, a multi level road construction said to rival some of the largest interchanges in the world.

The 40km Westlink M7 is Australia's biggest urban road project and is a key missing link in Sydney’s orbital road network of motorways.
The project's Environmental Impact Statement went on public exhibition from 8 January to 5 March 2001. On 28 February 2002, the NSW Minister for Infrastructure and Planning approved the project. In February 2003, the WestLink Motorway Limited consortium entered an agreement with the Roads & Traffic Authority to finance, design, construct, operate and maintain Westlink M7 motorway. The Federal Government is contributing $356 million towards the construction of this link with the remainder of the cost being met by the private sector.
The WestLink consortium has been selected to design, construct, maintain and operate the Westlink M7 for a total of 34 years, after which it is transferred back to the Government. The equity investors in the WestLink consortium are Transurban, Macquarie Infrastructure Group, Leighton Contractors and Abigroup Contractors.
A company comprising Abigroup Contractors and Leighton Contractors will undertake design and construction of the Westlink M7. The organisation is the Abigroup Leighton Joint Venture (ALJV).
The RTA coordinated the project's development, environmental assessment and planning approval phases. During the implementation phases, the RTA will administer the project deed and ensure that the consortium delivers the Westlink M7 according to the agreed scope and approval conditions.
