The Torrens to Darlington (T2D) section is the final piece of South Australia’s North-South Corridor
Raglan Avenue, Edward Street and South Road Network Upgrade
Street corner meeting – 4 May 2024
A new link road will be constructed as part of the Raglan Avenue, Edward Street and South Road network upgrade to help remove the current dog-leg movement of traffic travelling between Edward Street and Raglan Avenue and improve safety for road users.
This project forms part of the $850m Broader Network Upgrade package of works as part of the River Torrens to Darlington (T2D) Project.
Come along and meet with the T2D Project team to learn more about the Raglan Avenue, Edward Street and South Road network upgrade concept design at our local street corner meeting.
Drop by any time between:
10am to 11am Saturday 4 May 2024
Castle Plaza northern car park

T2D Project Urban Design Strategy
The River Torrens to Darlington (T2D) Project is the final 10.5km section of the North-South Corridor, and will complete 78km of non-stop, traffic light-free motorway between Gawler and Old Noarlunga. It is the biggest infrastructure project in the State's history.
On major infrastructure projects, good urban design should deliver great places for people to live, work and play in, while also minimising impacts to surrounding communities.
An Urban Design Strategy (UDS) has been developed for the T2D Project. It will be used to ensure high-quality urban design, landscape and public realm outcomes for the project.
Over the coming weeks there will be an opportunity to find out more about the UDS and give your feedback on what is important to you and your ideas for good urban design.
The UDS, and details about how you can give your feedback, is available on the T2D Project website.
To provide your feedback you can:
- complete a short survey online
- visit one of the information pop-ups
- register to attend one of the drop-in community sessions at the new central T2D Community Information Centre at 290 South Road, Hilton.
- Contact the project team via the details below to schedule an individual meeting.
Please provide your feedback by 5pm, 19 December 2023.

New Design for T2D
The T2D – consisting of two sets of twin tunnels, lowered and ground-level motorways, as well as overpasses and underpasses at key intersections – is estimated to cost $15.4 billion and be completed by 2031.
Key elements of the River Torrens to Darlington (T2D) Project were reviewed and changes have been announced to the project design.
Key proposed changes to the project include:
- Torrensville area – At the northern portal of the Northern Tunnels, near where the T2D Project connects to the North-South Motorway, a proposed large elevated roadway running parallel to the Brickworks Marketplace has been removed, with the motorway corridor moving to the east. Instead, a shorter, low-height structure over the corner of the Hindmarsh Cemetery will be constructed. This improvement, along with changes to the construction methodology, means the project will require less of Kings Reserve during construction than previously planned.
- James Congdon Drive/Deacon Avenue – An additional exit ramp for vehicles travelling north has been added near this intersection, providing access to Richmond Road and James Congdon Drive. This means vehicles travelling from the south, heading north to go to Adelaide Airport or the western suburbs, do not need to go through the Anzac Highway intersection, greatly reducing the number of vehicles on the surface road there and increasing travel options for motorists. An additional entry ramp at James Congdon Drive has also been provided for traffic wanting to enter the motorway and head south.
- Anzac Highway connection – The elevated ramp going over the motorway and South Road, before coming down onto the middle of Anzac Highway at Ashford to join with citybound traffic, has been scrapped. Instead, three ground-level right-turn lanes onto Anzac Highway heading towards the city will be provided, with an additional exit ramp from the River Torrens to Darlington motorway for northbound traffic, north of the Anzac Highway intersection. Right turns from Anzac Highway onto South Road – which were removed in the 2021 Reference Design – have been reinstated, acknowledging strong community feedback. This solution reduces traffic at the Anzac Highway intersection and the number of trees needing to be removed (approximately 35 instead of 116).
- Darlington connection – The southern portal of the Southern Tunnels will shift about 300 metres to the north to give traffic more distance and time to safely change lanes, while moving into and out of the new motorway. This provides the opportunity for better cross-corridor movement via a shared-use bridge, significantly reduces the duration of required closures of the Darlington motorway during construction (easing disruption for motorists), and reduces the length of the Southern Tunnels and the associated construction costs.
