Northern Expressway (South Australia)
Vorlage:Infobox Australian Road
- For the portion of U.S. Interstate 93 north of Boston also known as Northern Expressway, see Interstate 93 (Massachusetts).
The Northern Expressway is a proposed 23 kilometre long expressway that will be constructed in Adelaide, South Australia. Construction on the expressway began in 2008, and it will go from National Highway A1 (Port Wakefield Road, north west of Salisbury) to the town of Gawler, connecting to National Highway A20 (Sturt Highway). The new road will be built to four-lane standard and provide a faster route between Adelaide and Gawler, whilst reducing the amount of traffic on Main North Road. The Northern Expressway will consist of 23 km of new road, in addition to an 8 km upgrade of the existing Port Wakefield Road.
No route number for the new expressway has yet been released by the State Government. However possibilities include A20 (as an extension of the Sturt Highway) or M20.
Construction started in 2008 and is planned to be be competed by late 2010[1]. Part of the cost will be covered by the AusLink national transport funding.[2]
Northern Connector
It is also possible that the expressway will not end at Port Wakefield Road. In early 2008, the South Australian Government announced plans for the Northern Connector, an extension of the Northern Expressway, over Port Wakefield Road to connect with the Salisbury Highway link to the Port River Expressway. This section would also include a major diversion in the main ARTC interstate rail line, which would run down the middle of the expressway as far as Taylors Road. [3]
Construction
The largest road project undertaken in South Australia in at least sixty years, the expressway is being delivered at a cost of approximately $564 million jointly funded by the South Australian and Commonwealth governments. The Design and Construct contract has been awarded to the Fulton Hogan York Joint Venture, a partnership between trans-tasman contractor Fulton Hogan and South Australian based York Civil. The design joint venture, managed by Fulton Hogan York Joint Venture consists of Maunsell, SMEC and Dare Sutton Clark.
