Highway system

The Northern Expressway (route M2; formerly route M20), also known as the Fatchen Northern Expressway,[1][2] is a 23 kilometre long controlled-access highway in Adelaide, South Australia. It travels from Gawler (on National Highway A20, the Sturt Highway) to Port Wakefield Road (on National Highway A1). The road has been built to four-lane standard and provides a faster route between Adelaide and Gawler, whilst reducing the amount of traffic on Main North Road, which passes through the heart of the northern suburbs and is interspersed with frequent traffic lights. It also allows freight vehicles to avoid residential areas and go straight to Port Wakefield Road. Since March 2020, the North–South Motorway continues west of Port Wakefield Road and intersects the Port River Expressway (A9) to reach the harbour at Port Adelaide. These are the northernmost two parts of the North–South Corridor.

Cycling is not permitted on the Expressway. The Stuart O'Grady Bikeway is a sealed shared cycling and walking path adjacent to the eastern side of the expressway. The northern end connects to the on-ramp from Two Wells Road to the Gawler Bypass Road, and the southern end is adjacent to Port Wakefield Road at Mill Road.


The largest road project undertaken in South Australia in at least sixty years, the expressway was delivered at a cost of approximately A$564 million jointly funded by the South Australian and Commonwealth Governments. The Design and Construct contract was 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 consisted of Maunsell, SMEC and Dare Sutton Clark. The work included an 8 km upgrade of the existing Port Wakefield Road. Part of the cost was covered by the AusLink national transport funding.[3]

Construction began in 2008 and the road opened on 13 September 2010.[4]

The interchanges/bridges along the expressway were all named after famous battles in which Australian forces fought, such as Long Tan, Kokoda, Tobruk, Kapyong and Hamel.

In November 2013, one year after the death of prominent South Australian author and journalist Max Fatchen, the Northern Expressway was given the dual name "Fatchen Northern Expressway" in his honour.[1][2]

In December 2019, a Catastrophic bushfire started on the Northern Expressway at Angle Vale, This affected people in Hillier, Munno Para Downs, Kudla, Munno Para West and Gawler.

In February 2020, the on ramp from northbound on Port Wakefield Road was permanently closed. Three weeks later, the Northern Connector project was opened, continuing the freeway south from the Northern Expressway as the North–South Motorway.
