Major transport corridor for Adelaide
South Australia is in the midst of a major road infrastructure upgrade, with a number of projects along the north-south corridor at various stages of development.
The North-South Corridor is one of Adelaide’s most important transport corridors. It is the major route for north and south bound traffic through Adelaide, including freight vehicles, from Gawler in the northern fringe to Old Noarlunga, a distance of 78 kilometres.
The development of this critical corridor is being funded by the Australian and South Australian Governments. Currently there are three projects on the go – the Torrens Rd to Torrens River (T2T) project; the Darlington upgrade and the Norther Connector.
Combined the investment on these projects is more than $2.5 billion, and through its Industry Participation Project, the South Australian Government is committed to ensuring local workers and businesses reap the benefits.
Northern Connector Project
With a number of work packages currently open to expression of interest, the $985 million Northern Connector project will deliver a new 43km non-stop motorway connecting Port Wakefield Road and the already completed Northern Expressway to the Port River Expressway and South Road Superway.
The project includes:
- 15.5 kilometre motorway standard road with four road interchanges
- three lanes in each direction, with a speed limit of 110 kmph; and
- 16 kilometre path for cyclists and pedestrians.
Main works contractor Lendlease has established Northhub to help jobseekers from Adelaide’s northern suburbs secure at least half the estimated 480 jobs a year during construction.
Lendlease has also indicated a strong intention to identify local business capacity, especially Indigenous suppliers.
Further towards the city, the T2T, which began in 2015, is the most mature section of the corridor project currently under construction, with more than 150 work packages awarded - many going to local suppliers.
Federal and State Governments have each committed $448 million for construction of the T2T project, due for completion in 2018.
An alliance of CPB Contractors, Aurecon Australia and South Australian company York Civil – the T2T Alliance won the major works contract.
The end result will be a 4km, three-lane non-stop roadway (incorporating 3 km lowered motorway), reducing travel time through Adelaide’s inner North Western suburbs for commuters and freight.
As of the end of June 2016, the economic benefit to South Australia through works packages and labour was more than $147 million.
Darlington Upgrade Project
Meanwhile, on the other side of town, construction of the $620 million Darlington Upgrade has begun, with most of the work packages closed, but yet to be awarded.
Gateway South, a Joint Venture of Fulton Hogan and Laing O’Rourke, has been awarded the major works contract for the project. The consortium has committed to deliver more than $285 million in direct economic contribution to South Australia.
This stage will see about 3.3 kilometres of the existing Main South Road upgraded, including an underpass and free-flow interchange at the bottom end of the Southern Expressway.
The proponents for both the Darlington Upgrade and the Northern Connector engaged ICN early to identify local suppliers at the tender stage.
‘Through the whole life of these projects, the Government and the lead contractors have been committed to supporting local suppliers and local jobs as part of the Industry Participation Policy,’ ICN Supply Consultant Eddie Ivar said.
‘It is a great example of the value of getting involved at the tender stage for such large projects. Local suppliers have had the opportunity to engage in the projects earlier, whilst the lead contractors have been able to tap into local capabilities as they plan and deliver these large infrastructure projects.’
