The Torrens Road to River Torrens (T2T) Project is a significant part of the broader north-south corridor, that traverses some 78 kilometres through greater metropolitan Adelaide. In its current form, South Road is congested due to limited alternative north-south routes, freight movement between Gawler and Noarlunga, narrow road corridor width, increased development north and south of Adelaide, at-grade railway crossings and intersections with numerous busy arterial roads.

The T2T project seeks to address the transport deficiencies while enhancing the appearance of the corridor by proposing urban design outcomes that enrich the landscape and create an attractive and integrated public realm.

The project represents a great opportunity to build a community focused, memorable and integrated piece of urban infrastructure within the City.

The T2T project will deliver the following:

  • 4km length non-stop corridor upgrade
  • Improved east-west connections (pedestrian and vehicular)
  • Safe pedestrian links (raised crossings to connect east-west neighbourhoods)
  • A raised railway to remove at-grade crossings, improving traffic flow and safety
  • New landscape treatments within the road corridor
  • A series of public open spaces for community use
  • An upgrade of pedestrian and cycle paths
  • A series of gateway experiences at key intersections to assist in wayfinding and to enhance local character.


In line with the State Government’s strategies for urban renewal and regeneration of the inner city with projects such as Bowden Redevelopment, St Clair and Hindmarsh, and acknowledging the unique urban character of the surrounding villages, we see this as an opportunity to reconnect local neighbourhoods and create a viable and useful city connector, a catalyst for further renewal of the inner west.

The design has been developed around the following guiding principles:

  • Memorable – attractive and eye-catching, without being dominant
  • Walkable – safe and comfortable for pedestrians, cyclists and people with a disability
  • Sensitive – to local culture and heritage
  • Sustainable – enduring, greening, regenerating, useful

Noise walls

Minimisation of project related construction and operational noise and vibration is a major consideration for the project.

A range of treatment measures to reduce noise have been incorporated into the design including:

  • Selection of asphalt types
  • Lowering the road
  • Road surface
  • Installation of acoustic barriers on the side of the rail overpass

Noise barriers have been installed along the road corridor to offset short-term and long-term noise impacts for the local community.

Construction activities will comply with requirements of the Department of Planning, Transport and Infrastructure Road Traffic Noise Guidelines and the Environmental Protection Authority Guidelines for the assessment of noise from rail infrastructure.
