M7 Westlink Motorway

Linking the M2 at Baulkham Hills, the M4 at Eastern Creek and the M5/Hume Highway at Prestons.

The motorway bypasses 48 sets of traffic lights, allowing a journey from south of Liverpool to West Pennant Hills in less than 30 minutes. In addition to improved travel times for motorists in Sydney's west, the M7 has taken an estimated 60,000 vehicles per day off the existing western Sydney road network.

Roads and Maritime initiated the M7 Motorway project in response to a need to connect Sydney's existing motorways (the M2, M4 and M5 motorways) and complete a substantial part of the NSW Government's Sydney Orbital Strategy.

The M7 Motorway was designed to dramatically reduce travel times across western Sydney and to provide a significant part of the expanding Sydney Orbital Road network.

The motorway was built in conjunction with major upgrades to local roads, delivering significant benefits to local communities.

Key features

The Light Horse Interchange

A 55 metre illuminated mast at the M4/M7 Light Horse Interchange at Eastern Creek honours members of Australia's famous Light Horse Brigades. Two thousand commemorative red batons 'sprout' from native grasses on the median strips of both the M4 and M7 Motorway interchange approaches, signifying the predominant regimental colours of red and green and helping approaching motorists to easily identify the Light Horse Interchange.

The M7 shared pedestrian and cyclist path

Accessible to pedestrians and cyclists, Australia's longest cycleway stretches almost 40 kilometres between Prestons and West Baulkham Hills, providing a healthy and environmentally beneficial option for pedestrians and cyclists. The shared path is separated from traffic and includes safe crossings at all intersections. The shared path links to other regional cycle networks, including Western Sydney Regional Park, the Fairfield to Homebush Bay Cycleway and bicycle lanes on the M2, improving the ability of cyclists to commute between regional areas.

Extensive landscaping

Approximately 800,000 plants were cultivated as part of the M7 Motorway project, including a mixture of native and exotic species. Local native plants were selected for much of the M7 Motorway in order to maintain local ecology and biodiversity.


This part of the project, a new park was provided in Abbotsbury at the start of the 40 kilometre pedestrian and cyclist path. The Plough and Harrow Precinct is built on former grazing land and contains a mix of open and treed spaces.

It incorporates environmental initiatives including water reuse and bushland regeneration with a variety of visitor amenities such as picnic shelters, two large pavilions and a playground.
