To ensure the T2D Project unlocks Adelaide's traffic network, there will be $850 million worth of additional network and amenity upgrades along and around the final 10.5km section.

Intersection and road upgrades

UpgradeDescriptionMore info
Manton Street and Adam Street junction upgrade

Additional left turn lane for Manton Street into Adam Street (eastbound) to provide additional capacity for city-bound traffic.

Selgar Avenue link

Construction of a new link road to provide a link road for motorists and residents at Selgar Avenue to the Tonsley precinct.

Grange Road, Holbrooks Road and East Avenue intersection upgrade

Creating a four-way intersection to improve capacity for a key parallel route during the T2D Project construction and over the longer term.

Raglan Avenue, Edward Street and South Road network upgrade

Realigning Raglan Avenue north to create an upgraded four-way intersection with Edward Street.

This will create a safe and direct linkage between Edward Street and Raglan Avenue to reduce congestion and unlock development opportunities.

James Congdon and Sir Donald Bradman Drives upgrade

Introducing right turn lanes from James Congdon Drive into Sir Donald Bradman Drive (city-bound) to improve network connectivity and options for motorists to access the CBD.

 

South Road surface road additional north and southbound lanes (between Anzac Highway and Manchester Street)

South Road surface road to be predominantly three lanes from Anzac Highway to Manchester Street to improve traffic flows and network delays.

 

Richmond Road duplication and Railway Terrace intersection upgrade

Duplicating Richmond Road from South Road to Railway Terrace with an upgrade to the Railway Terrace intersection.

This will address current congestion issues and increase future capacity for this key link between the CBD and the western suburbs.

 

Marion Road and Richmond Road

Capacity improvements to improve access for vehicles travelling west on Richmond Road towards the Adelaide Airport.

Haulage upgrading

Upgrading key haulage routes to the project construction site to prevent degradation of roads caused by vehicle movements to the site for delivery of materials and removal of spoil.

 
Tram overpass modifications

Increasing spans and constructing new footings to accommodate the lowered motorway and create improved amenity for the community.

 

Shared-use path to cross over the motorway and South Road, Tonsley

Providing an elevated shared-use path to enable pedestrians and cyclists to safely cross South Road.

 

South Road rehabilitation and resurfacing

Amenity improvements including road resurfacing, footpaths, vegetation, lighting and undergrounding of powerlines.

These upgrades will support economic uplift for local business by making South Road a safer, easier and more attractive place to live and work.

 

Local area traffic management

We will be working with local council and communities to improve safety on local roads near the T2D Project.

We will assess active travel improvements, traffic management, safety and amenity across the T2D Project area to minimise the potential impacts across the community from the T2D Project both during and after construction.
