A9 (Sydney)
The A9 is the outer western Sydney Bypass connecting Campbelltown to Windsor. It was formerly designated Metroad 9, which was one of Sydney's Metroads. “A9” is used as a route number designation for the entire length, however the road falls under numerous local names. From Windsor to Campbelltown: The A9 applies to Narellan Road from the Hume Motorway interchange to Camden and the complete stretch of The Northern Road from Camden to Windsor via Penrith. It crosses the Great Western Highway and M4 Western Motorway near Penrith. The A9 is also the major link between the International  Regatta Centre at Cranebrook and the M4 Western Motorway. It was upgraded just before the Sydney 2000 Olympics. History. The A9 route was first known as State Route 69. State Route 69 was a state route linking to via Sydney's western suburbs, along Putty Road, the current A9, and Appin Road. It was replaced by Metroad 9 in December 1998 and consequently State Route 69 was split into two sections. The northern section (Putty Road) connected Windsor to Singleton. The southern section (Appin Road) connected Campbelltown to Wollongong via the Princes Motorway. In 2013, as part of the alpha  numeric route scheme, Metroad 9 was decommissioned and replaced by A9. Also, the northern section of State Route 69 (Putty Road) was decommissioned while the southern section (Appin Road) is now route B69. Road upgrade. As part of the Western Sydney Infrastructure Plan, of The Northern Road will be upgraded to a minimum of four lanes between The Old Northern Road at Narellan and Jamison Road at South Penrith. The project is being delivered in six stages, with the first stage at Oran Park completed in April 2018. In April 2020, the Northern Road was also realigned between Mersey Road  and Eaton Road at Luddenham, to facilitate the construction of Western Sydney Airport. On 16 July 2020, The Northern Road and Bringelly Road interchange opened including a realignment of The Northern Road. On 13 December 2020, The Northern Road was realigned between Elizabeth Drive and Eaton Road was opened to traffic, bypassing Luddenham. The rest of The Northern Road upgrade was completed through 2021, with the final upgrade opened to traffic in December 2021. Future replacement. As part of economic development of western Sydney, including the construction of the Western Sydney Airport at , the road was proposed to be upgraded  to a grade separated motorway. The proposal, known as the M9 Outer-Western Sydney Orbital motorway, would link the M7 at with the Central Coast via , and . As part of the State Budget 2014–15, the NSW Government announced a $5.5 billion road package for Western Sydney. It includes $4.6 million for planning the M9 Motorway. The preferred corridor for the motorway was expected to be announced later in 2014 before plans are made for reserving land. The corridor is now known as Outer Sydney Orbital.
