The largest road project undertaken in South Australia in at least sixty years, the expressway was delivered at a cost of approximately 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. Construction began in 2008 and the road opened on 13 September 2010. 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. 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.

Northern Connector
In early 2008, the South Australian Government announced plans for the Northern Connector, an eight lane connector roadway, linking the Northern Expressway and South Road. This plan involved the construction of a four-way cloverstack interchange at the Port River Expressway / South Road intersection. This project was also proposed to include a major diversion in the main ARTC interstate rail line, which would run downthe middle of the new connector freeway between Dry Creek, South Australia and Taylors Road at Waterloo Corner. The funding for the road and shared path components was announced in September 2015, with construction started in late 2016. There was an open day before the road opened on 7 March 2020.
