The North-South Motorway is an incomplete planned motorway traversing the inner western suburbs of Adelaide from Wingfield in the north to Bedford Park in the south. It is planned to be a non-stop north-south route overlaying the same motor traffic corridor as South Road by grade separation. The motorway is to be the central section of Adelaide's North–South Corridor, being flanked north and south by the Northern Expressway (including the Northern Connector under construction) and Southern Expressway, respectively.

Adelaide City in South Australia

Adelaide is the capital city of the state of South Australia, and the fifth-most populous city of Australia. In June 2017, Adelaide had an estimated resident population of 1,333,927. Adelaide is home to more than 75 percent of the South Australian population, making it the most centralised population of any state in Australia.

Wingfield, South Australia Suburb of Adelaide, South Australia

Wingfield is a suburb situated north of Adelaide. It lies between the Port River Expressway on the north and Grand Junction Road on the south. The suburb borders Dry Creek to its north and east, bounded by the Gawler railway line and Adelaide-Port Augusta railway line on the east. The North-South Motorway and Dry Creek-Port Adelaide railway line both cross the suburb. Wingfield is named after R. W. Wingfield, the private secretary to Governor of South Australia, William Jervois.

Purpose

The Australian Government, through the Nation Building Program project, committed $500 million and the South Australian Government $432 million to the North–South Corridor over five years. This funding allocation recognised that South Road is the only continuous link between the northern and southern suburbs as well as the spine connecting Adelaide’s major inter-modal transport hubs – Adelaide Airport, Islington Rail Terminal, Port Adelaide and Outer Harbor. [2]

South Australia State of Australia

South Australia is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of 983,482 square kilometres (379,725 sq mi), it is the fourth-largest of Australia's states and territories by area, and fifth largest by population. It has a total of 1.7 million people, and its population is the second most highly centralised in Australia, after Western Australia, with more than 77 percent of South Australians living in the capital, Adelaide, or its environs. Other population centres in the state are relatively small; Mount Gambier, the second largest centre, has a population of 28,684.

North–South Corridor, Adelaide road route in and beyond Adelaide, South Australia

The North–South Corridor is a series of road projects currently under construction or planning which travel through Adelaide, South Australia that will eventually form a continuous link from Old Noarlunga in the outer southern metropolitan Adelaide suburbs through to Nuriootpa in the inner northern rural area around the Barossa Valley, a distance of over 100 km, aiming to be without a single stop by 2030.

Adelaide Airport airport in Adelaide, Australia

Adelaide Airport is the principal airport of Adelaide, South Australia and the fifth-busiest airport in Australia, servicing just over eight million passengers in the financial year ending 30 June 2017. Located adjacent to West Beach, it is approximately 6 km (3.7 mi) west of the city centre. It has been operated privately by Adelaide Airport Limited under a long-term lease from the Commonwealth Government since 29 May 1998.

Planning

As of October 2018 the planned motorway is divided into five sections for the purposes of construction, three of which are unconstructed or incomplete. From north to south the sections are labelled:

South Road Superway

Highway system

The South Road Superway is an elevated motorway in the northern suburbs of the South Australian capital city of Adelaide. [1] The 2.8 km elevated roadway rises just north of Taminga Street, Regency Park and goes over Days Road, before access ramps at Grand Junction Road, then continues over Cormack Road and the Dry Creek railway line to join the intersection of the Port River Expressway, Salisbury Highway and in the future, the Northern Connector. In 2009, an announcement was made to build an $812-million elevated roadway above South Road from just north of Regency Road to the end of South Road where it joins to the Port River Expressway and Salisbury Highway. It was constructed over a 4 km section of South Road at a cost of A$812 million and opened in early 2014. The Superway was the biggest single investment in a road project in South Australia's history. [3] The Superway was the second stage of the North–South Corridor upgrade and 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. The Superway will continue northwards through the Dry Creek salt pans once the Northern Connector is completed at its northern end.

Regency Park is an inner-northern suburb of Adelaide, 8 km from the City Centre, in the state of South Australia, Australia. It is located in the City of Port Adelaide Enfield, and is adjacent to Wingfield, Angle Park, Ferryden Park, Kilburn, Prospect, Dudley Park and Croydon Park. It is bounded to the north by Grand Junction Road, east by the Gawler railway line, south by Regency Road and to the west by Days and South Roads. The postcode for Regency Park is 5010.

Grand Junction Road is the longest east–west thoroughfare in the Adelaide metropolitan area, and is located approximately 8 kilometres north of the Adelaide city centre. Travelling from the Port Adelaide region, it is mostly a double-lane sealed road running 21 kilometres to the base of the Adelaide Hills. The western end at the intersection of Old Port Road, 300 metres east of a causeway which separates the Port River from West Lakes. The 2.4 kilometre section of road that continues west of Old Port Road to Semaphore South is named Bower Road. The eastern end of Grand Junction Road is in the suburb of Hope Valley, at the intersection of Hancock Road and Lower North East Road, just before the latter proceeds into the Adelaide Hills, past Anstey Hill Recreation Park and on towards the towns of Houghton and Inglewood.

The Dry Creek to Port Adelaide railway is an eight-kilometre east–west line running through Adelaide’s north-western suburbs. The line is managed by the Australian Rail Track Corporation (ARTC) and is an important link between Port Adelaide, Pelican Point and the main interstate rail routes which link Adelaide with Melbourne, Perth, Darwin and Sydney. Prior to 1988, a limited local passenger service operated, stopping at five intermediate stations along the line. Since May 1988, the line has been freight-only.

Construction

South Australian civil engineering and construction company, Bardavcol, was awarded the early works local roads contract for the South Road Superway, with the design and construction contract awarded to Urban Superway Joint Venture, comprising the John Holland Group, Macmahon Contractors and Leed Engineering & Construction. [4]

John Holland Group

The John Holland Group is a construction, tunnelling, rail, building and services provider with operations in Australia, New Zealand, South East Asia and the Middle East. Headquartered in Melbourne, it is a 100% owned subsidiary of China Communications Construction Company, a Chinese state owned enterprise.

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. [5] Construction was completed March 2014. The southbound lanes opened early February 2014, with the left turn entry from Port River Expressway opening on 31 January 2014. [6] The northbound lanes opened on 13 March 2014. [7]

Regency Road to Pym Street

Connecting the South Road Superway to the T2T lowered motorway, this short section of road currently has 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 beginning at the start of 2019 and 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. [8] Completion of this section was committed by the state and federal governments on 1 May 2018. The announcement stated that the cost would be A$354m but did not state an expected completion date. It will include an overpass of Regency Road and a pedestrian and cycling connection over the freeway near Pym Street. There will be three lanes each way on the non-stop road and another two lanes each way on the surface road to provide access to community and businesses. [9]

Around 2007, there were plans to construct a tunnel under Grange Road, Port Road and the Outer Harbor railway line, and construction was to start after the underpass had finished, but these plans were later scrapped. In 2013 the State Labor government in partnership with the Federal Labor government announced an upgrade from Torrens Road to the Torrens River, upgrading approximately 4 km. The upgrade would feature a new, lowered road under Grange and Port Roads. This will provide a non-stop route through the area for passing traffic and reduce delays to east-west travel. A parallel surface road along the length of the lowered road to connect the majority of local roads and arterial roads to South Road as they do now and a rail overpass of South Road for the Outer Harbor line to ensure the service doesn't interrupt traffic along the new route. Construction started in 2015, with the project expected to be completed by the end of 2018. [10] [11]

The project work was extended in December 2015 to include an underpass of Torrens Road, at no additional project cost or time. [12]

The lowered motorway opened to traffic on 29 September 2018. [13] [14] [15]

River Torrens to Anzac Highway

As of October 2018 no funding has been allocated to construction of the Torrens to Anzac Highway portion of the planned road corridor. This section contains it some of the busiest intersections of inner suburban Adelaide, as it goes directly past the city. It includes intersections with Henley Beach Road and Sir Donald Bradman Drive. In 2018, the possibility was raised that this section could be completed by tunnelling under the existing alignment due to the tight spaces between expensive and heritage listed properties. [16]

Anzac Highway to Darlington

Although the Anzac Highway to Darlington portion of the road corridor is intended to be upgraded to include non-stop north-south traffic flow before 2030, As of October 2018 there are no detailed plans and no funding has been allocated to construction. [17] Issues with this section include the intersection of South and Daws Roads in St Marys and the 5 intersections within less than a kilometre around Castle Plaza in Edwardstown. The Gallipoli Underpass at Anzac Highway, which is only considered an interim solution, and the grade separated junction at Cross Road, including the Seaford railway line, are anticipated to be upgraded separately in advance of the rest of this section of road. [18] :16

In August 2018, the possibility was raised that this section could be completed by tunnelling under the existing alignment. [16]

Gallipoli Underpass

In 2005, along with the decision to make a free flowing South Road, a decision was made to build an underpass for South Road to go under Anzac Highway. Construction of this started in 2007, and it was named the Gallipoli Underpass, in line with the ANZAC theme. The underpass opened in March 2009, and to cut down on delays due to construction, an overpass was also built within the same time frame for the Glenelg Tram line just half a kilometre to the south, which also opened in 2009, significantly removing delays from this area.

Emerson Overpass

Approaching the Emerson Overpass, heading south in April 2012

Between 1982 and 1984, the Emerson Crossing was built, taking South Road over Cross Road and the Seaford railway line. For a long time, this was the only grade separation on South Road, and one of very few in South Australia, removing congestion with Cross Road traffic and the railway line. Increasing frequency of commuter trains are resulting in vehicle bottlenecks that are anticipated to worsen as queues on the exit ramps to Cross Road can extend into the through lanes on South Road. The rail crossing could be closed for up to 20 minutes in the peak hour. [18] :54

In 2010, it was announced that an interchange would be built in Darlington, to provide better access to the Southern Expressway, as well as Flinders Medical Centre, Sturt Road and Ayliffes Road. This project was the basis for the Southern Expressway getting the go-ahead for duplication, but then in 2011, this project was scrapped, due to budget issues.

The plan was revived in 2014, [19] with early works commencing late in 2014 for an expected completion in 2018. [20]

A joint venture ("Gateway South") of Fulton Hogan and Laing O'Rourke was awarded the major works contract for the project in January 2016. The scope was expanded from earlier plans and will now upgrade 3.3 kilometres (2.1 mi) of Main South Road by creating a lowered non-stop road with surface-level service roads. There will be three lanes each way connecting from the Southern Expressway and the lowered road, which will pass underneath Flinders Drive (access to Flinders University and Flinders Medical Centre), Sturt Road, a bridge connecting Mimosa Terrace (Clovelly Park) and Sutton Road (Bedford Park) mainly for local traffic, grade separation at the Ayliffes Road and Shepherds Hill Road junction, and at Tonsley Boulevard. It will also provide separate cycling and pedestrian paths on each side of the corridor. The associated Flinders Link Project will extend the Tonsley railway line across this corridor to Flinders Medical Centre. [21]
