The Northern Connector (proposed route M20) is a 15 kilometre long proposed expressway in Adelaide, South Australia. It will travel from the North-South Motorway (National Highway M2) at Wingfield to the Max Fatchen Expressway (M20) (previously known as the Northern Expressway) as part of an ongoing plan to develop a continuous freeway grade road between Old Noarlunga and Nuriootpa known as the North–South Corridor. The road is proposed to be built with three lanes in each direction and provide a faster, safer and less congested route over the section of the North-South Corridor between South Road and the Max Fatchen Expressway.[1]
This would involve the construction of a complex interchange at the Port River Expressway / North-South Motorway intersection[2] and would also include a major diversion in the main ARTC interstate rail line, which would use the same corridor between Dry Creek, South Australia and Taylors Road at Waterloo Corner. The federal government proposed that it could be the state's first toll road.[3]
2008 plans
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, with three intermediate interchanges.[4] This would involve the construction of a four-way cloverstack interchange at the Port River Expressway / South Road intersection. The project would also include a major diversion in the main ARTC interstate rail line, which would run down the middle of the new connector freeway between Dry Creek, South Australia and Taylors Road at Waterloo Corner.[2]
September 2015 announcement
On 14 September 2015, the Premier of South Australia, Jay Weatherill and Prime Minister of Australia Tony Abbott announced that the road component of the project would start construction in early 2016. The federal government will provide A$788M towards an expected total cost of A$985M. The project is now only three lanes each way (was four in 2008 announcement), and only two intermediate interchanges (Globe Derby Park interchange will not be built in 2015 plans). The road will not be subject to direct tolls, but South Australia will become a testing ground for a "network fee" which involves charging trucks based on road use and impact in place of high registration fees.[5] This construction includes the road and shared path, but not the rail component.[6] The rail corridor would now be reserved on the western side of the road, rather than down the median strip.
Preliminary works
Part of the early work for the project involved realigning the intersection at Kings Road and Bolivar Road. Kings Road is a significant cross-suburban route (State Route A18) feeding from McIntyre Road past Parafield Airport. It terminated at a T-junction with Bolivar Road only 300 metres (980 ft) from the Bolivar Road and Port Wakefield Road intersection. Prior to the main Northern Connector construction, the intersection would be realigned so that they meet at a new two-lane roundabout constructed on vacant land south of the former intersection. Kings Road would become the main road that continued to the intersection at Port Wakefield Road, and beyond to the Northern Connector interchange.[7]
In January 2016, work was commenced carting earth and brine mud to build embankments across the former salt flats. This is required to allow it to settle properly before the road can be built on top.[8]
