It connects three Metroads: M5 at Prestons, M4 at Eastern Creek and M2 at Baulkham Hills. It opened on December 16, 2005, eight months ahead of schedule.

[edit] History

Western Sydney is the fastest growing part of the Sydney metropolitan area. The ring roads Ring Road 5 and State Route 55 - and later State Route 77 - originally meant to bypass Sydney, had instead become primary arteries for the western suburbs.

By the late 1990s and first decade of the 21st century Western Sydney had become the third biggest producer of Australia's GDP, after the Sydney CBD and Melbourne. The growth of industrial and residential areas brought about a massive increase in traffic on its local roads. This led to the planning of the Western Sydney Orbital which, among its original purposes, was to serve the stillborn second international airport at Badgerys Creek.

Due to the strategic importance of Western Sydney, the Federal Government decided to fund a freeway which, in addition to becoming the main thoroughfare for Western Sydney, would also be part of a National Highway Sydney Bypass, linking the Sydney-Newcastle Freeway in the north and Hume Highway in the south-west via the western suburbs. This change of emphasis led to the Western Sydney Orbital being renamed Westlink M7.

With its opening, Metroad 7 between Liverpool and Beecroft was transferred from Cumberland Highway to Westlink M7. Westlink M7 was the first Sydney motorway to be marked with the alphanumeric M7 rectangular shield rather than the hexagonal Metroad shield.

On 25 December 2005, just 9 days after opening, the M7 suffered its first fatality: a 12 year old boy died at Cecil Park when the 4-wheel drive he was travelling in rolled down an embankment and onto Elizabeth Drive, almost crushing another car.

In Sydney's southwest, the M7 starts at the Hume Highway/M5 South Western Motorway (Roden Cutler) interchange at Prestons [1]. It follows a new track until the Elizabeth Drive/Wallgrove Road junction, Abbotsbury. From then on it runs parallel to Wallgrove Road until the Wallgrove Road/Great Western Highway junction, interchanging with the M4 in what is known as the Lighthorse Interchange - Australia's first four level stack interchange. Continuing north, it leads to Minchinbury and follows alongside Rooty Hill Road North until Dean Park. The final, northernmost section of the M7 runs in a roughly easterly direction until ending at the M2 Hills Motorway junction.

The M7 passes through suburbs including Hinchinbrook, Cecil Park, Abbotsbury, Horsley Park, Eastern Creek (where it crosses and intersects the M4 Motorway), Oakhurst, Quakers Hill, Acacia Gardens and finally ends at Baulkham Hills where it joins the M2 Hills Motorway. The section from Dean Park to the M2 follows the original North West Freeway corridor.

M7 is claimed to reduce transit time across the western suburbs of Sydney by at least one hour.

[edit] Tolls

It was built as a fully tolled, gateless motorway employing electronic payment, the toll free period ending on January 15, 2006. The toll was originally 29.91 cents per kilometre, capped after 20 kilometres at $5.98, but on April 1, 2006, this increased to 30.07 cents per kilometre, capped after 20 kilometres at $6.01. Currently until June 30, 2008, the toll is 31.97 cents per kilometre, capped at $6.39. The toll is adjusted quarterly according to the CPI.
