half a kilometre to the south, which opened in 2009, significantly removing delays from the area. In August 2007, Prime Minister John Howard announced that South Road was to be included in the AusLink National Road Network, and pledged $1 billion in funding for the project between 2007 and 2020. North–South Motorway The North–South Motorway is an incomplete motorway intended to replace South Road as Adelaide's primary north–south roadway. Running along the same road corridor as South Road and extending further north, the motorway has been progressively constructed in stages. As of November 2020, approximately 22 km of the total 35 km length has been completed. The first section of the motorway, known as the South Road Superway, was announced in October 2009. It is 3–4 km of elevated motorway running from the Port River Expressway to the intersection with Regency Road. The project started in 2010 and was completed in early 2014. Following the 2013 Australian federal election, the section of South Road between Torrens Road and the River Torrens was identified and funded for an upgrade. 4 km of lowered motorway was built between the northbound and southbound lanes of South Road. The Torrens to Torrens lowered motorway started construction in 2015 and opened to traffic in 2018. The project included replacing a level crossing of the Outer Harbor railway line, with a new bridge in 2017. The Darlington Upgrade, an extension of the Southern Expressway through Bedford Park by use of a similar lowered motorway concept, was also identified at this time. Both of these upgrades involved land acquisition to widen the road corridor, surface grade local carriage ways on the edges, and a lowered central roadway carrying the free-flow traffic below the crossing routes. The Darlington Upgrade began construction in 2016 and was opened in 2020. An upgrade of Regency Road to Pym Street, the gap between the elevated South Road Superway and the (then) almost-completed Torrens to Torrens lowered motorway, was announced in May 2018, to be jointly funded by the state and federal governments. Main construction began in late 2019. The overpass opened at reduced speeds in March 2021. Preliminary plans for the final section stretching from the River Torrens to Darlington, which would use a combination of deep-bored tunnels, lowered motorway and surface-level motorway, were announced in late 2020 and are still under investigation.
