Superway delivered a 4.8 kilometre section of freeway grade road, including a 2.8 kilometre elevated roadway, from the Port River Expressway to Regency Road. Along the way, it passes over the Dry Creek-Port Adelaide railway line, Cormack Road, Grand Junction Road and Days Road, with exits at Grand Junction Road and Days Road. South Road was previously designated as part of route A13, when South Australia moved to the alpha-numeric road route system in 1998, with the section between the Salisbury Highway in Wingfield and Grand Junction Road in Regency Park designated as part of National Highway A13. When the South Road Superway was opened in 2014, route A13 was replaced entirely by route A2. As the section of South Road designated National Highway A13 was replaced by the South Road Superway, this was replaced by National Highway M2. This was modified to route M2 in 2017, to match designs used across the rest of the state. Construction South Australian civil engineering and construction company, Bardavcol, was awarded the early works local roads contract for the South Road Superway. The design and construction contract was awarded to Urban Superway Joint Venture, comprising the John Holland Group, Macmahon Contractors and Leed Engineering & Construction. Construction of the local connector roads was completed in early 2011, with the completion of construction of Gallipoli Drive. This road replaced South Road as the main distributor road in the area during construction. Construction of the superway proper commenced in early 2011. Construction was completed in March 2014. The southbound lanes opened in February 2014. The left turn entry from the Port River Expressway opened in January 2014. The northbound lanes opened in March 2014. Regency Road to Pym Street After construction of the South Road Superway and the Torrens-to-Torrens lowered motorway, this section of road was left with two traffic light intersections, including Regency Road, a controlled pedestrian crossing, and access to local side streets. It was reported in May 2017 that completion of this section would cost $400 million, with construction to begin at the start of 2019 and be completed by the middle of 2022. This would complete 47 km of freeway from Gawler to the River Torrens. The state government said it was seeking 85% of the cost to be funded by the federal government, which had not committed to the spend. Completion of this section was committed to by the state
