The name "A9" is just the route allocation for the route as a whole. In fact, the A9 route runs along a whole series of roads. From Windsor to Campbelltown:

  • Macquarie Street
  • George Street
  • Richmond Road
  • The Northern Road
  • Narellan Road

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 Singleton to Wollongong 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.[2] 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
Main article: Western Sydney Infrastructure Plan

As part of the Western Sydney Infrastructure Plan, 35 km (21.7 mi) 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.[3][4] The project is being delivered in six stages, with the first stage at Oran Park completed in April 2018.[5] 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.[6][7] On 16 July 2020, The Northern Road and Bringelly Road interchange opened on 16 July 2020, including a realignment of The Northern Road.[8]

Future replacement

It is proposed that as part of economic development of western Sydney, including the construction of an airport at Badgerys Creek, the road would be upgraded to a grade separated motorway. The proposal, known as the M9 Outer-Western Sydney Orbital motorway, would link the M7 at Casula with the central coast via Camden, Penrith and Windsor.

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 is expected to be announced later in 2014 before plans are made for reserving land.[9]

gollark: I would be surprised if there weren't human-competitive autorouters around.
gollark: IIRC it works by arranging modules, not individual transistors, so presumably it's quite comparable to PCBs.
gollark: It was for within ICs, not boards, but no, it beats humans significantly.
gollark: Didn't Google make a very good automatic routing thing recently?
gollark: I mostly just put up with slightly bad software all the time.
